I have specified jvmargs for pmd, findbugs and ant_opts is set to
1024M.

Thanks Koshuke, 

I consistently see OOME around the same phase in a build. So, i think it just needs a big memory...

I have given jvmargs as -Xmx1024m -Xms1024m

but still im getting the same issue.

can u plz tell me where can i do this:

Run JVM with -XX:+HeapDumpOnOutOfMemoryError so that JVM will automatically produce a heap dump when it hits OutOfMemoryError.

Thanks,

Did you change the memory settings for your job or the master? Since the warnings are processed on the master you may need to change the settings on the master, too.

Note that the analysis suite currently is not capable of handling projects with #warnings > 10k, see http://issues.jenkins-ci.org/browse/JENKINS-1960. How many warnings do you have?

Hi Ulli,

Now I have changed the memory settings in manage hudson (please refer attachment)

I'm getting the following error

Please let me know if i am doing wrong and where can I change the settings...

I don't think that this option helps.

How do you start Hudson? Can you add the parameters to that command? E.g. java -jar jenkins.war -Xms256m -Xmx1024m

[Sravan kumar Revuru]

No, Its deployed in tomcat 6. 

So I generally start the server and follow the link   http://localhost:8080/hudson/

Thanks,

Then you need to assign more memory in Tomcat for that application.
