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.
