I have just installed the Adobe Master Suite on my work PC and the one program I need the most (Dreamweaver) hangs at 100% at all times after opening. ALL other Adobe CS5 programs DON'T do this, and remain at a low 0-20% during idle.
This just started happening about a a day ago, and before that was performing normally. I have also just installed new memory (3gb) and figured it must due to faulty memory. Yet I replaced my sticks with the old ones and still the problem continues, while all other programs work fine.
I'm assuming it's either some memory leak or virus or ... who the heck knows, but I tried re-installing the program again and booting into safe mode but both to no avail. I also deleted the personal config file, but this also did nothing. Also, this was not doing this before hand but only happened a day ago. I literally have no idea what I could have done but I know for sure that my PC can run this program as I've already designed an entire site with this version.
Are there any programs I can use to figure out the culprit or find out what is wrong with Dreamweaver.exe?
Win 7 ultimate 32
Same problem here... been using CS5 Dreamweaver for a couple months, worked great... then recently it got really slow and became a resource hog. Right now, it's taking about 35% of my 3.4GHz quad-core's CPU to switch between code and design views... and it takes 3 to 5 seconds. I have 4 GB of DDR3 1600 RAM and no other apps open except Windows 7 resource monitor. This is something new, because it wasn't happening two or three weeks ago. I'm running ESET's NOD32 antivirus, but I have the same issues even when I tested without my antivirus.
Same issue. Up to date DW CS5. The CPU usage seems tied to the number of files open. Right now it is pegged at 50% (of my dual core) since I have 12 items open in code view only (no preview). As it close them, the CPU usage goes down until I have only a couple open and it is almost idle.
Clicking ANY menu in the system causes CPU to drop down to 0%.
When DW is at 50%, my entire system slows down. I have a Core 2 Duo 2.8GHz, 6GB, Windows 7 64-bit. Problem has persisted across system reboots.
I would REALLY wish that Adobe get's off the butt on this one. This has been an outstanding problem for almost a year.
If adobe wishes to work with me directly, I would be more than happy to help! They can contact me on my adobe email addr.
Same here... I just started using Dreamweaver a few months ago and it keeps spiking my CPU to 50%, even when I am not ever using it. Adobe's tech support solution was to shut down the program. So this has been a bug for the past year? I thought Adobe was a reputable company, but not fixing a major bug like this for over a year, and their tech support solution to shut the program down is making me wonder. Every time the CPU spike, the fan in my laptop speeds up, it's driving me nuts.
Windows 7 Pro 32bit
2.6GHz Dual Core Intel
It is strange that it has been such a long-term issue, while it seems to be reproducable. If I start DW and open my typical gamut of files, it pretty much always spikes and drags my entire machine down. Actually I make a habbit of shutting down DW before bed so that my machine doesn't act as space-heater all night.
Do you happen to use coldfusion files / javacsript or all html/css?
Mainly html/css files. Some perl and php but it seems to happen on all of them. I can not beleive with our help they could not figure this out easily and get it fixed. This might be my last Adobe purchase.
Hey Books. Actually adobe did contact me for more information, and I am replying to one of their emails today, so at least they are trying to reproduce the error. Do you also notice that as you open more files, the CPU usage goes up? 20%, 40%, then maxes at 50% (or 100% if you have only 1 core)? Right now I have 10 files open (mix of XML, CFM, CFC) and my CPU is maxed around 50% which drags the entire system down, and yes, makes my fan go nuts.
You have Win7 32 bit, so my thought that it was a 64-bit issue goes out the window. You find that once it his 50%, it stays there correct?
It does seem to get worst the more files I open. My CPU maxes out at around 50% (dual core) but normally only for a few seconds, 10 seconds max. That is the part that is really driving me nuts. It even does it when I have files open and I'm not even working with the program. I do not have any test servers set up which is something tech support said could cause the CPU to spike. I also have Adobe Fireworks, Photoshop and Acrobat installed. If we can figure out what is common between our 2 system, that might help them pinpoint the problem.
I also do not have any testing servers configured. Question. Have you been experiencing any file access issues on your Win7 box (in or outsite of DW)? Ever have a hard time saving in DW (saying that it can not access the file)? Ever try to save an attachment and have it say that it could not be read from temp? How about doing something like a local SVN add or many files (hundreds) and having it continuously error out with permission issues, which go away by simply trying again?
I started out on this laptop with a 500GB drive, and now I run a 160GB solid state from Intel, and I have reinstalled since. My machine has been having strange random access issues and one thought might be that it could be tripping up DW with some cache building process if the OS has locked the file.
Also, my DW is set up for coder view, with a minimized panel on the left, and line numbers down the side of the code view. My CPU spikes occur with in "code" view, so real-time preview is not an issue.
I have "Site Cache" disabled in my site preferences, but this issue happens across all of my sites.
I tried running DW as administrator, but I experience the same problems. It seems like my spikes seem to happen after 8 or more files are open (doesn't matter what type).
This is the second MSG that I sent to adobe:
Well it seems to happen with any file type, not just CFMs. Right now I have open an XML, 4 CFCs and 6 CFMsI am seeing CPU sitting at 48% (memory not changing, at 85MB private, 135MB working). It has been doing this for a few minutes now. I've left it going for 10 minutes. I closed the CFM files one at a time, and the CPU stayed at 40-50%. But as soon as I closed another specific CFM file, the CPU dropped right down to 4% even with the other 6 files open.
I opened up another random CFM file and it spiked to 50% for a second and back down, and I opened up a second CFM file and now it is back to 50% for a couple of minutes. I closed the first CFM file and we're still at 50%. I waited a minute and it dropped down to 6% on its own.
I closed ALL files, opened up a new site, and opened 8 HTML files. The CPU is now at 50%. I closed two more HTML files, and it dropped down to 4% again (with 6 HTML files open).
Just to make sure that the issue wasn't with any specific content, I coped the SAME HTML file to multiple files: index.html, index - Copy (2).html, etc, wit hteh following HTML:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
I began opening these one by one. Again, these are the EXACT same HTML content, and I started with no files open (DW at 0%).
Opened 1 - 0%
Opened 2 - 1% sustained
Opened 3 - 2% - 4% sustained
Opened 4 - 2% - 5% sustained
Opened 5 - 3% - 6% sustained
Opened 6 - 4% - 6% sustained
Opened 7 - 4% - 8% sustained
Opened 8 - 40% - 50% sustained
After about 1 minute, this dropped down to 5% - 9% sustained.
This then goes back up to 50% on it's own, then back down, then I just leave it there, and in a minute, it goes back to 40-50%.
Closing a bunch of the HTML files down and leaving it at 4 files open seems to resolve the processor spike again
No to all your questions about file access issues. I have never experiences any file read, write, or save issues.
My DW is also set up in code view, a minimized panel on the left, and line numbers down the side. It always happens in code view. I also have Site Cache disabled.
There are several different scenarios discussed in this thread. I have not been able to reproduce any of them.
For the scenario where "DW was normal for a while after installation, then the CPU suddenly started spiking", it sounds like a cache may be corrupted, an extension may be causing a problem, or even some combination of preferences.
Start by taking a look at this TechNote:
Note: all of the following actions should be done with DW Shutdown!
Execute Step 4 to clear the FileCache.
If you still see the problem execute Step 12. This clears all caches, disables all extensions, and resets some preferences. If you have any extensions installed, enable them 1 at a time to try to isolate the problem.
If you still see the problem, perform Step 12 again, and also delete the Registry key which is here on Windows:
Change preferences 1 at a time.
Hope this helps,

The above comment should clear the problem but I have to ask:
Everyone seems to be reporting problems on Core2 systems, many of which can just barely run Windows 7 out-of-the-box. Do you have at least 4GB of system RAM? I am predicting that less than 4GB will create problems, as Dreamweaver starts hitting your boot drive for virtual memory, which also taxes your CPU as it swaps in and out of virtual.
Win 7 and OS X 6+ are 64-bit systems and you ought not consider 2GB an appropriate amount of RAM any more. I am recommending a minimum of 4 GB and, on a system that you're using for serious production, 16GB—dedicating at least 3GB to 32-bit Dreamweaver and 4GB to 64-bit Photoshop. Remember, every application you run is going to take more away from the applications you're working in.
I typically have Dreamweaver, Photoshop and two browsers open when I am working, along with my email client and possibly a couple of other applications running. This is on a dual quad-core Mac Pro with 16GB of system RAM. And since I'm using CS3, everything is 32-bit and cannot see more than 4GB of RAM.
Re-reading this sounds like "blame the victim," and I don't want to come off like that in this forum, but Adobe (and everyone else) may be assuming that, for actual production work, we have dedicated a little more hardware.
Instead of making customers spend more money on upgrading their hardware, why not make software that is more efficient and not a big resource hog. You will never have customers complain about software being too fast and efficient.
Here is Dreamweaver CS5's system requirements:
Intel Pentium® 4 or AMD Athlon® 64 processor
Microsoft® Windows® XP with Service Pack 2 (Service Pack 3 recommended); Windows Vista® Home Premium, Business, Ultimate, or Enterprise with Service Pack 1; or Windows 7
512MB of RAM
1GB of available hard-disk space for installation; additional free space required during installation (cannot install on removable flash-based storage devices)
1280x800 display with 16-bit video card
Broadband Internet connection required for online services
So far Randy's suggestions seemed to have worked for me... thanks for your help Randy.
Those are minimum requirements.
My commentary is meant to suggest that, if you are using Adobe's tools for actual production (like you don't particularly want to wait for a pokey computer), you should have more kit.
In order to use Dreamweaver, you don't actually have to have a web browser, but I don't know anyone who would suggest that is wise. In order to use Adobe's InDesign you don't have to actually own a printer, but it would be a good idea if you actually want to see your work on paper.
Running 6GB over here. Monitoring the OS, with DW, Photoshop, Coldfusion, Quickbook, MySQL, Firefox, Thunderbird, Word, Excel, SQLYog, Outlook and chat programs running simultaniously, I've yet to consume the entire 6GB. The only way I can eat it all up is if I start booting virtual OSs in VMware.
I wouldn't say that DW is particularly resource consumptive with DW only taking about 200MB-300MB of RAM on my system, and it should run OK on even a 2GB system on Win 7 64bit, though more RAM is obviously ideal. I am not sure what you mean by Core2 barely running win7 out of the box. This machine runs a P9700 2.8GHz Core 2 Duo, and typically screams with Windows 7. I've never had any install trouble with Core2 systems and Win 7.
I ran through Randy's recommended instructions at http://kb2.adobe.com/cps/405/kb405604.html
1. I deleted WinFileCache-530B2A19.dat with DW closed. I opened DW and opened 14 HTML files. Still the CPU Spikes to 50%, and drops off after about a minute or so but keeps spiking.
2. I did a recreate site cache and opened 16 HTML files, spikes for about a minute.
3. I went to disable the "Coldfusion" extention that comes with Adobe Coldfusion 9, but the CS5 extention manager lists no extentions for DW. Not sure what that means.
4. I didn't do a reinstall, but again this happened on my last OS install.
Question. Do you guys (who experience this problem) use snippets? I have a bunh of them setup. Maybe that is another commonality.
Well, I am using CS3 so I don't experience problems with CS5. I have too much in process right now to switch.
When I say a Core2 system is just barely able to run Win 7 I mean Core2 systems as typically sold with standard RAM, GPU and hard drive installed, not Core2 systems that have been upgraded, preparatory to a Win 7 installation. Everyone likes to talk about how cheap pee cees are and then moans and groans when the computer can't get out of its own way. Production systems need more than 2GB of RAM.
I do not use code snippets. But that ought not overtax the CPU.
1. I deleted WinFileCache-530B2A19.dat with DW closed. I opened DW and
opened 14 HTML files. Still the CPU Spikes to 50%, and drops off after
about a minute or so ...
When opening 14 files, this does not sound to be out of the ordinary.
... but keeps spiking.
Thankfully, I think that most systems come with 4GB minimum these days, since RAM is so cheap. Ahh I remember buying an extra 8MB of ram for my 486 for some astronomical amount...
Randy, yes when I open files DW will spike momentarily, which is normal, but then immediately drop off. The problem that we are having is that it gets stuck at 50% CPU for minutes, sometimes indefinitally until you close out all but 6 or so files.
If anyone wants to see this problem first-hand, I uploaded a video capture of me opening files, with windows task manager, here:
I began having this problem with Dreamweaver a couple of weeks ago. My software is CS5 Master Collection
Windows 7 Ultimate 64Bit
Dell Precision T5400 Workstation
Xeon CPU X5460 3.16GHz (4 Cores)
NVIDIA Quadro FX3700 512MB
1.5TB 7200 RPM HDs
Dreamweaver would max out one core after opening at least two files. Didn't seem to matter whether the files were HTML, PHP, CSS, etc.
The problem for me appeared to be corupt prefferences. I followed these steps and eliminated the problem entirely:
Restore preferences | Dreamweaver CS4, CS5 - http://kb2.adobe.com/cps/839/cpsid_83912.html
Just confirmed that I have turned this feature off (unchecked 'Enable related files'), and my CS5 still maxes out one core just sitting there with about 6 files open on my Core 2 Duo with 6GB. Restarted since. Same problem.
OK, so this is not a permanant solution. a few weeks after following the instructions listed here: http://kb2.adobe.com/cps/839/cpsid_83912.html, the problem returned. Surely the Dreamweaver team does not expect us to go through these steps every few weeks?
I use DW, like most others I imagine, in a production environment. I can't have it max out a CPU core just sitting there. Please tell me someone at Adobe is aware of and working to resolve this BUG!!!!
I experience this too on a Win 7 x64 machine running Dreamweaver CS5 11.0 build 4964 (Dreamweaver uses 1/4 of my quad-core processor). However, it only occurs WHEN I HAVE AN .XML FILE OPEN. As soon as I close the .xml file, the processer returns to normal.
I implemented the quick registry change shown in the previous post (http://kb2.adobe.com/cps/887/cpsid_88742.html), and it seems to have fixed it based on my cursory testing.
Hope this helps!
DW CS5 build 4964, Win7 x64 Core2 Duo, 6GBs, and DW still eats up 1 full core just sitting there, from time to time. I -THINK- that I had tested this issue and ruled out xml as a triggering file type to cause this issue. I mostly edit .XML and .CFM files so it is possible that it is an XML file issue, but I think that it was happening with CFM files only.
I will watch this and if I see a CPU spike, I will close my XML and see if it drops down. I know -FOR SURE- that I was able to close out CFM files and reduce the processor load (almost file per file the CPU would drop down).
I have implemented the recommended change (http://kb2.adobe.com/cps/887/cpsid_88742.html) and I will keep an eye on the CPU usage.
While your solution is great for fixing DWs hang time when opening certain documents, it did not help the CPU hit that CS5 has on computers when documents are open.
I have two screenshots showing how DW affects my CPU. See below:
In Screenshot 1, I have two documents open, an HTM file, and PHP file. Dreamweaver is slamming one of my cores.
In Screenshot 2, I have closed all files, and the problem goes away.
Should this be reported as a BUG?
I just submitted a bug report for this issue. Maybe if enough reports are sent, Adobe will fix this issue.
Here is the Bug Report link: https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform
Well, this is not a fix, but it does solve the 100% Core consumption... I have found that if I toggle "Live View" on and off, the Core consumption drops to near 0%... And stays at that level... I can repeat the solution on every page that opens and pushes my core up to near 100%... Click on "Live View' and I see and instant drop in core consumption... All is good after that... Hope that Helps... Adobe, why is the software doing this?
I can confidently say that one cause of CPU usage spike from opening Dreamweaver is from Site-Specific Code Hinting. I have a Core i5, Windows 7 64bit, and only one WordPress site with code-hinting enable, my CPU usage spikes around 70% and holds there for up to minute upon loading Dreamweaver.
If I delete the site specific code hinting config file, then Dreamweaver acts normally and has normal CPU usage upon loading. This CPU usage seems pretty extreme. I hope this is some sort of error rather than normal behaviour but I have my doubts. Can anyone else confirm this happens on their system?
I'm having the same problems here. I've noticed over time that Dreamweaver has taken increasingly longer to boot.
I opened up my Resource Monitor to see what exactly was bottlenecking with Dreamweaver. It appears at a glance that Dreamweaver does some intensive file-writing which maxes out the CPU and the hard-drive...causing the entire system to lock up.
When booting Dreamweaver, I noticed the most intensive read/writing was occuring in: C:\Program Files (x86)\Common Files\Adobe\Adobe PCD\cache
I also noticed a one-time occurence of Dreamweaver reading all the files in my site. I'm using since I have the "Files" pane opened, it was reading that folder and caching all the files/folders into a cache (as I tried to reproduce Dreamweaver to read those files again, I could not)
As of now, Dreamweaver CS5 opened without any files or projects open runs at 164,000 K which is massive for an idling program!
I've done a few things though that seems to resolve most of my Dreamweaver startup issues.
1) Followed step 4 here: http://kb2.adobe.com/cps/405/kb405604.html (deleted the cache file)
2) Followed Adobe's advice and added this registry edit: http://kb2.adobe.com/cps/887/cpsid_88742.html
3) Reset my DW panels to a default view. I closed ALL panels first, exited Dreamweaver....rebooted Dreamweaver several times...then set the panels back to "Coder Plus"
I really hope Adobe addresses these issues with a patch of some sort. I use several other Adobe programs and don't experience the drastic hanging and resource hogging that Dreamweaver diplays. All Adobe programs take up quite a bit of memory, but for some reason Dreamweaver is the only one that locks up during it's startup.
Also, here are my specs if an Adobe engineer needs them. Adobe employees can contact me if they want any further information related to my experiences with this issue:
