Running Grails application.. java.lang.OutOfMemoryError: PermGen space

[neoplanet]

Dear all,

I'm using SpringSource Tool Suite Version: 2.6.1.RELEASE Build Id: 201105041000 and have problems with Java OutOfMemory. (Grails Project Version 1.3.7)

I follow the tutorial to increase the Java memory allocation without sucess:
http://artur.ejsmont.org/blog/conten...sts-and-tomcat

I change the workspace from a NFS place to a local disk directory, same problem.

My machine have Ubuntu 10.04 LTS x86 4 Core with 4GB of ram.

This problem starts when I add 70 new files to the directory src/java.

PS: I don't have root access on machine.

Should I test the last version of the STS?

Best regards,

[neoplanet]

Your post says that the error is "java.lang.OutOfMemoryError: PermGen space"

However the stacktrace you posted shows a completely different error: "java.io.FileNotFoundException: /home/rd/pedro.ambrosio/Documents/workspace-sts-2.6.0.RELEASE/ehealthcom/application.properties (Too many open files)"

So what is the actual problem? A permgen space problem or a "too many open files" problem.

It's important to be clear about that since they are really totally different problems.

If its a file limits issue, perhaps you could try upping the open files limit. I found a little article that explains how to do this in linux.
http://lj4newbies.blogspot.com/2007/...pen-files.html

If you are still seeing the problem after upping the limit, it could be there's some badly behaved piece of code that is opening but not closing files. In that case, please raise a Jira issue here
https://issuetracker.springsource.com/browse/STS

Since that is something we should look into.

If it's a permgen error, I guess you probably pasted the wrong stacktrace. So please find the right one (it could help in determining what process is running out of permgen).

Dear Kris De Volder,

Sorry about this situation/confusion, but I (think that I) have both problems.
I'll increase the number of open files and I'll report the result.

PS: "java.lang.OutOfMemoryError: PermGen space" message appears when I try run-app the application. If I war the project and deploy in Tomcat I don't have any problem.

Thank you for your response,

Best regards,

[Kris De Volder]

So to be clear... the perm gen error happens if you use the menu "Run As >> Grails command (run-app)" right?

That probably means that our launch configurations generated for this scenario allocate insufficient permgen memory for your app. I take it may be a fairly big app?
Unfortunately, there's no way right now to change that (for the Run As >> Grails command"). See also this open bug report: https://issuetracker.springsource.com/browse/STS-1697.

You should be able to create a special Grails launch configuration through "Run As >> Configurations" and then you can modify the meory setting by adding to its VMArgs there.

Yes, if I run war I don't have any problem and the war file works OK in the Tomcat

I upload to the project 70 new java files in src/java

Unfortunately, there's no way right now to change that (for the Run As >> Grails command"). See also this open bug report: https://issuetracker.springsource.com/browse/STS-1697.

I'll also try and tell you the result.

Thank you and best regards,

[Kris De Volder]

OK, great if you can try that!

Also FYI, I fixed the bug https://issuetracker.springsource.com/browse/STS-1697 now, but that fix didn't make it onto the nightly update site yet.
