Case:

I have to redeploy many times a day a WAR on a WebLogic 10 server, using Hotspot (Sun JVM) with Java 6. After some cycles deploy/undeploy, Hotspot crashes with the following error:

java.lang.OutOfMemoryError: PermGen space

A short explanation

The error seems to be linked to the garbage collection. From what I could read on the web, static objects used in CGlib (and/or jars depending on the library, such as the wide spread Hibernate, Spring, etc.) are the source of the crash.

Fix

Switching HotSpot to Oracle/BEA’s JVM, aka JRockit, makes the error (almost) disappear.
Alternatively, if you can’t change the JVM, a workaround consists in upgrading the following parameter on JVM launching:
-XX:MaxPermSize=256m
