PermGen error

[oneworld95]

We're getting this error when we redeploy a Seam application:

2009-07-02 10:11:30,745 WARN [org.jboss.system.ServiceController] Problem starting service jboss.web.deployment:war=forms_new_employee.war,id=-1855897005
java.lang.OutOfMemoryError: PermGen space
....
2009-07-02 10:11:59,745 ERROR [STDERR] java.lang.OutOfMemoryError: PermGen space

We've bumped up the memory and ran into the issue again and again; from what we've read, no matter how much memory you allocate to it, it's only a matter of time before the problem occurs between JBoss and the Sun JVM. Is the solution to switch to the JRockIt JVM?

Here are two articles that suggest switching the JVM, among other solutions:

That looks like a leak somewhere. Check the application in your war file.

Thanks for the reply. How do you track down the leak?
