In Jboss 3.2.1 I often encounter OutOfMemoryErrors on our jboss installations. I realized that if no redeployments happen the JBoss instance even being on heavy load works great forever. Once I begin to often redeploy applications I finally get OutOfMemoryError no matter if I specified -Xmx300m or -Xmx800m. Can anybody run a memory profiler on a redeployment process? I tried to do it with OptimizeIt and I always get +1Mb of heap after each redeployment. Most new objects are of type Object[] and are referenced from WeakHashMaps (which is ok I guess), from inside some classes of Xerces parser and many more. I cannot of course judge whether these new references are caused by the leak or not. As far as I remember I had no such problem when I used Jboss 3.0. As always, I am ok to offer any help I can.
