Flash Builder hangs a lot

[leshes-cciqBe]

Guys, seriously, Flash Builders hangs in all our machines like 4-5 times a day. If you press CTRL+F2 to terminate the debugging session, it hangs 1 in 2. I think that you have serious problems with the multithreading.

Debugging is hellish, more or less 10% of the times it can't connect with the debugger and gets stuck in the 57% (waiting to connect).

The bridge between the debugger and the flash player is weak! For instance, If you close the browser before the connection with the debugger, flash builder doesnt realize it and hangs (not responding...)

Why do you have so many problems with the Flash Player connection??? You need to drop the current approach and choose something more solid!

In overall, the flash builder experience is poor.

I still remember the bug:

http://bugs.adobe.com/jira/browse/FB-16153

But you didn't launch a new flex in order to solve it. We waited for Flash Builder to come. And it is still weak!!!!!!!!!!!!

Mike Morearty has let??? Who is working in Flash Builder? Please, make it rock solid!!!

And, by the way, I love Flex 4. The spark skinning. The states syntax. The two-way binding. It is incredible! You have improved over the Microsoft work in WPF. It is simpler and more elegant. Please, repair Flash Builder.

Hello,

We have the same issue here. It freezes very often in debugging mode. This behaviour started today/yesterday.

[Anirudh Sasikumar]

Hi,

Thank you for your feedback.

Some questions:

1. Are you on Windows/Mac?

2. Which browser do you use?

Cheers,

Anirudh

P.S: I had replied to this post on Sep 16, but the forum ate my email response. Posting it via the web now.

[leshes-cciqBe]

Windows.

It hangs specially with Firefox.

I have seen it hang in many computers. Yesterday I was in a friend's office, he showed me the project they are working on and, of course, flash builder hanged once. It should be easily reproduce-able in your machines, you only need to develop/debug medium-sized projects with it, but professionally, not anecdotically, for 8 hours a day. You will see it happen a few times a day.

In my opinion, the debug flash player communication with flash builder is weak.

[Anirudh Sasikumar]

Hi,

Flash Builder communicates with the debugger over a socket. If the browser is closed, the socket shuts down and the debugger figures it out from the stale socket. At no point is a hang expected.

Would it be possible for you to run jstack (bundled with the Java JDK) on Flash Builder when it hangs and attach its output here?

The jstack dump would help us nail this. The syntax is:

jstack (PID of FlashBuilder.exe) > jstackdump.txt

P.S: I totally appreciate your enthusiasm and understand your frustration. Customers like you help us fix Flash Builder and make it a great product.

Cheers,

Anirudh

[leshes-cciqBe]

Anirudh,

I'm more than willing to help. I too want Flash Builder to be as perfect as possible. Next time it happens I'll post the dump from jstack.

The problem is not after Builder has connected to the debug player, it is before. It keeps looking and looking for the player to start.... but the player won't start, for whatever the reason, and Builder gets stuck in the 57%. You have to manually open the "Progress" tab and manually abort the operation... sometimes it will abort, sometimes it won't... you need to close the whole flash builder...

The other complete hang (not responding...) I have found is when you try to terminate the debug session (CTRL+F2). I will post everything I can.

Thanks

My Flash Builder 4 (Version 4.0.1 build 277662) also hangs (1-2 times per day).   It can hang randomly, but often I think it's related to the Content Assist window getting stuck.

I run it on Windows 2003 Server SP2 with 1.5GB RAM.     I generally launch apps to IIS 6 and use IE7 for the browser.

My only recovery is to kill the Flashbuilder task and start it up again.     I'm pretty much in the "save and save often" mode nowadays.    Especially when I'm doing anything that might bring up the Content Assist window.

I've included a jstack trace.

Thanks.

Hi Philip,

On first glance, the log seems to indicate that the Java VM is hung. This usually happens Java is about to run out of memory.

I'll pass this jstack dump to the editor guys as well - they would be able to infer more from this.

Thanks,

Anirudh

[francispotter]

I had this problem (the 57% hang) this morning using Flash Builder 4.5 (i6 prerelease) on OSX.

Hitting stop in the "Progress" view and trying again did nothing.

Restarting the browser did nothing.

Switching to a new browser did nothing.

Restarting the machine did nothing.

Then I figured out that the Main.swf file was missing. It had never been built, for some reason.

I don't know *why* Main.swf wasn't built, but at that point it was an easy workaround to just edit one of the files (forcing a rebuild) and then run again. It worked.

Seems like the debug process should be able to figure out if the .swf is missing, and handle it more effectively than just hanging at 57%.

Anyway, hope this insight helps others.

[Daniel_Pride]

I am on a Mac not windows but having the same problems, along with way to many other bugs.

an the other gentleman said... PLEASE FIX FLASHBUILDER

[ratnawe]

Similar to the experience of philip_leb I've experienced hang-ups with the "Generate ... handler" function - which is a very common task. I would estimate a 1 in 10 chance that FB hangs when using this function. This is pretty inconvenient since I have to save my projects very often in order to not lose any data. The hang-up expresses itself as a freeze of FB and a FlashBuilder.exe process that suddenly makes my case fan blow a loud storm > high cpu consumption. What I cannot say yet is if the debugger is playing a role there.

I will try to figure it out and also make a jtrace.

I'm using a Windows machine (btw. I'd love to see FB for Linux coming back ) I'm mostly using Firefox.

Thanks!

[RobotMonkey]

FB 4 hangs for me about every 20 to 30 minutes and if you wait about 5 to 7 minutes it will start working again. It happens when typing, when pasting, when doing just about any ordinary task in the editor. I thought maybe it was freezing when it was trying to call the intellisense dialog, but now it crashes even when pasting. It is the most frustrating development environment ever considering it doesn't try to type ahead on variable names and crashes constantly.

I'm running it on a Windows 7 64bit machine.

[idman]

I switched browsers (Chrome to IE) and it works fine now. Before it hung at 57% as others mentioned. Quick fix, but don't know what the problem was.

[Shailen_TJ]

Windows XP SP3, Flash Builder for PHP 4.5, Firefox 4

It is so frustrating that Flash Builder hangs whenever it feels like to, for no reason at all. There are no particular actions that I am doing that causes the freeze.

My FB project is getting huge, has a lot of modules. My database is also big. However, I do not think that FB should cease to behave nicely when the project grows.

If any particular logs are needed, I will provide them.

[RobotMonkey]

If you are having frequent crashes, like I did, you might want to uninstall all anti-virus software and try it again. My problem, which took uninstalling twice, was due to Webroot Security Suite.

Good luck!

[VPenades]

I am having the "57% hang" problem too...

I've been working with flex since the early days of flex3, and a few weeks ago we upgraded to Flash Builder 4; we are in the process of overhauling a fairly large project from flex 3 to flex 4, and a short while after we upgraded from flex3 to flex4 we began experiencing the 57% problem.

Essentially: when you open flash builder and the project does not have any error, it compiles and displays the page, if we keep the project compiling, we can run 2 or 3 further debug sessions.... but the moment there's the slightest problem, any attempt to run or debug the project gets stuck at 57%.

From that point, the only way to recover is: Disable automatic rebuilds; clean the project, exit flash builder, and load it again. We can't keep developing like this.

Environment:

Flash Builder 4.5 standard, Windows 7, FireFox 3.6.18

We also did what was suggested in this page:

http://labs.ultravioletdesign.co.uk/flexflash-builder-not-connecting-to-debugger-hangs-at-57/

but the only thing we got was that, sometimes, just, sometimes, a project cleanup solves the problem... until the next build.

Another symptom: when it gets stuck at the 57% , if we leave the window open long enough, a display message is shown, telling that it's been unable to connect to flash player.

A friend of mine, who also uses Flash Builder and of course is fighting it every day, has recommended not to upgrade to 4.5. They don't solve any of the stability issues, and he said to me that he has the feeling that they are even worse.

This remains unsolved, so another questions has been asked.  http://forums.adobe.com/thread/906671?tstart=0

I got significant improvement by turning of 'Enable Design Mode'

Hi,

We have been developing a new cloud based application in Flex for over two years and there have been a lot of hurdles. But, we still love it so it would be cool if Adobe put just a tiny little bit more focus onto it and onto Flash Builder.

With versions 4.1, 4.5 and 4.6 the Content Assist appears to 'pause' sometimes for a fews seconds and on occasions it has stopped working altogether. I have seen it stop for days and then come back to life. pressing CTRL+Space did nothing. Highlighing a variable didn't then hightlight all occurances of that variable, and so on. I agree with nishantkyal that switching off Design Mode in v4.6 did seem to make some difference to performance.

In a word we have found the debug experience to be too difficult. I suggest Adobe launch another process to monitor the existing debug processes to look for hanging, network issues, etc. This monitor process could tidy up the connection, break it, reconnect it, report problems, etc. Rather than the launch and hope it doesn't hang approach. This would make it more resilient to memory shortages, firewalls, anti-virus, wierd browser differences, o/s configuration and bugs, etc. A lot of people run a lot of different hardware, O/S and browser (and the rest) configurations that might cause issues with the debug process.
