Please Help - Randomly HTTP 503 Internal server error

Ryan Luo Aug 9, 2012 12:04 AM

Hi all,

I have a Coldfusion 10 standard Edition installation with MSSQL 2005 on Windows Server 2008 R2 server about 2 week old.

It is one of my live server and it is dealing with medium to high volume of traffic.

Since deploying this server, it has been getting random HTTP 503 internal server errors,

which require the entire server restart (as coldfusion application server, IIS restart will not able

to resolve the problem). Within this two weeks, sometimes it can last for couple of days without problem,

and sometimes it require 4-5 times server restart within one day.

I can't replicate the error on demand, but I could paste one of the windows server event log here:

Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7afa2

Faulting module name: isapi_redirect.dll, version: 1.2.32.0, time stamp: 0x4f745a78

Exception code: 0xc0000005

Fault offset: 0x000000000000cd68

Faulting process id: 0xfd4

Faulting application start time: 0x01cd745ad58e3393

Faulting application path: c:\windows\system32\inetsrv\w3wp.exe

Faulting module path: C:\ColdFusion10\config\wsconfig\1\isapi_redirect.dll

Report Id: 144b3231-e04e-11e1-8e6d-00505687001e

And I started suspecting the problem is because the connector comes with coldfusion 10, based on one of the bug reports from apache

https://issues.apache.org/bugzilla/show_bug.cgi?id=48826.

Based on the information in log file, they are pretty similar.

Any suggestions on how to fix this random server error would be greatly appreciated!

Many thanks

Ryan

Is there anything in the CF or Tomcat logs?

Hi Adam

Thanks for your reply, I couldn't find anything useful in tomcat log, beside the system event log I have supplied in my original post, here is the cf log when 503 error happened.

sorry to ask again, but is there any thing I could confirm this issue whether because of a faulty connector delivered with cf10 or something else
thanks again

Use "LocalSystem" for DefaultAppPool identity.

Luo,

You're not the only one having this problem. I removed CF9 after migrating to CF10 and all systems failed. I get the same results as you. I'm going back to 9.

Ryan Luo Aug 19, 2012 9:53 PM (in response to van u)

Thanks for your reply Van
I am not really understand the IIS setting, but the server machine serves multiple sites , each site is using a application pool and every application uses "ApplicationPoolIdentity" as their Identity. There is a "DefaultAppPool" uses "ApplicationPoolIdentity", but I don't believe it has been used though.
My problem is, we are using a network login for the coldfusion application service instead of "Local System Account", due to the file access permission in our network.
Should I change all the application pools to use "LocalSystem"? Will this affect the fille access required by the coldfusion services?
Thanks in advance

Thanks for your reply djkhalif
I can not roll back to the version it was, because it was using coldfusion 6.1 and we need some new functions from later version, plus the coldfusion 10 is the only licence we have.
It is affecting all my production servers, and I have to baby sitting them everyday 24/7. Kind frustrating.
Thanks for your information again

I'm having the same issue, IIS 7.5 on Windows Server 2008 64bit. The issue will cause the application pool to crash specifically when doing a cffile action="upload". My logs are showing the exact same errors as yours both in ColdFusion and in the Windows Event viewer.

Is there a bug submission somewhere where I can vote this issue up?

Thanks for your information bittersweetryan
Is this happening in your development environment or it is happening in a production environment?
Are you able to replicate the crash yourself?

It is in a brand new server that is being tested for production. I can replicate the crash every time, the server will work fine until I do a cffile action=upload. The application pool will then crash causing the server to stop responding. This is on a Windows 2008 Server 64bit, IIS 7.5, and ColdFusion 10.

Your problem is a bit different to mine, I am sure I do have lots cffile when action is upload in my application, and that part will be called multiple times. But the server only crash randomly and I can't replicate the error myself.
It went down 4 times in an hour this morning and I am frustrating a lot and lots of pressure at the moment.

@bittersweetryan Aug 24, 2012 12:06 PM (in response to Ryan Luo)

I think I reduced my problem as far as I can go. Its not the CFFILE operation itself, its with a http request with a large amount of content, such as doing an XHR file upload. This causes the IIS connector to tomcat to throw numerous errors. If your thread pool is set to die after x number of errors the pool will crash leaving the server unresponsive. My solution was to do traditional form based file uploads instead of using XHR.

Ryan, I am having the same issue. I tried the change that Van suggested above, so we'll see that it works. I used the advice in the article in his link to change the account that the IIS 7.5 application pool runs under. You can learn more about changing it here: http://technet.microsoft.com/en-us/library/cc771170%28v=ws.10%29.aspx . I would never have found it otherwise--it is tucked in application pool > advanced settings > process model - identity. Change to LocalService and hope for the best.

If you solve it though some other method, please post as I have 5 servers ready to go into production once this issue is solved.

Klevenson
Since you have tried to solve the problem by changing the identify to LocalService, would you able to tell me whether it is working or not?
I am not able to do such changes, since my servers have already into production.
My temperate solution is increasing the number of error IIS can handle before shut itself off.
It is in application pool > Advance setting > Rapid-Faill Protection - Maximum Failures
Since I have found the IIS will shut itself off after 5 errors been sent from connector, by increasing the number here, it temperately solved my problem (but my event log still full of errors from connector)
I am also trying to contact Adobe in a formal way to discuss about this issue.

We're getting the same issue on our CF 10 server too. It'll run fine for an hour or two, then fill up the coldfusion-error.log with about 4Mb of this error - over and over. Often the system will choke at this point.
I can not say whether or not this is related to our ongoing issue with support: trying to get CF10 and ASP4 to run at the same time:

Upon further review of the logs here, it's possible that these events could be triggered by CF's invocation of flash forms (ie CFFORM type='flash'). They seem to coincide in close proximity.

AlHolden,

I've noticed that the connector definately crashes when there is a http request with a large content payload. If I do a HTML5 file upload the server will crash immediately. Do your forms submit a large amount of data in the post?

Yes Ryan, it seems to be fairly consistent with a large request.

I earlier stated that the issue might have been related to flash form invocation/compilation - but it could also be due to the fact that these forms are starting off with some grids that are pretty heavily populated with data on first load.

I just posted on the other thread that I had tried the an alternate connector (tomcatiis.riaforge.org).
It seems to work well with ASP.net and does not require any ISAPI support, though it does require a little more work to install since it is 3rd party.
I used instructions from this blog post:

With my experience, 503's are caused by slow pages eating up the worker threads. I recently installed CF10 and noticed right off the bat that it is slower that CF9 so the combination of the two either caused or exacerbated your problem. Now I just installed CF10 and have not done any fine tuning yet. When I upgraded to CF9 I remember similar problems that fine tuning solved -- but the problems did not show up right out-of-the-box like they have with CF10.

Talal/Steve,

It's obvious that you did not read the bug report linked to above. This has nothing to do with server load. You can crash a server with zero load instantly with this bug. ANY CF10 server on IIS. It's not a configuration issue or a capacity issue. It's a crashing bug, plain and simple.

Are you running the latest update?

Does it help if you enable "Cache Web Server Paths" setting in the Caching page of the ColdFusion Administrator?

The bug report for 3222748 claims that as a workaround. If not, I would go here and vote up the bug, assuming your issue is producing the same error messages as the ones stated there.

AlHolden, I've enabled that option (we run a single server) so I'll see if that helps. The problem is intermittent and with no regular frequency, so hard to tell when it will happen next. We run update 11.

Someone also mentioned changing the application pools to run as "LocalService" - not sure if that will help either. It's a bit like black magic trying to get CF to work properly

Perhaps it could be stated "It's a bit like black magic trying to get CF to work properly with IIS"

CF is basically a Java J2EE application. IIS is a Microsoft application. I think it's more a game of cat and mouse, than black magic.
