[jboss-user] [JBoss Messaging] - OutOfMemoryError with JBoss Messaging

I am getting java.lang.OutOfMemoryError after a few hours when running a load test with the following setup. JBoss AS 4.2.2 GA JBM 1.4.0 SP3 JBoss Remoting 2.4.0.CR1 (Pinto) JDK 1.5.0_06 JVM arguments : -verbose:gc -XX:+PrintGCTimeStamps -XX:NewRatio=1 -Xms1024m -Xmx2048m -XX:PermSize=128m -XX:MaxPermSize=256m -XX:+UseParallelGC -Dsun.rmi.dgc.client.gcInterval=120000 -Dsun.rmi.dgc.server.gcInterval=120000 The Full GC times increase from 1 second at the beginning to 30 seconds in the end. The Old generation space gets filled to the max of 1GB and after sometime the Eden space is filled up to its max and GCs cannot claim any more space. The memory usage is very stable when testing with JBossMQ. The jboss remoting objects seem to be growing throughout the test. When testing with JBossMQ the jboss remoting objects are pretty stable and not nearly as many instances as with JBM. I have tried with JBoss Remoting version 2.2.2.SP4-brew as recommended in the JBM 1.4.0 SP3 documentation and I get the same behavior. Below is a heap snapshot towards the end of the test. 769946 .. 168189k . char[] 2814906 . 98961k .. java.util.HashMap$Entry 936726 .. 88564k .. java.util.HashMap$Entry[] 2008055 . 54907k .. java.lang.String 936446 .. 51211k .. java.util.HashMap 434925 .. 25114k .. java.lang.Object[] 634584 .. 22309k .. java.util.Hashtable$Entry 1788960 . 20964k ..
