Jboss Version: 4.2.3GA
JBoss WS version: 3.0.5 GA
We are running a portal application (using JBoss portal) in a production environment; The portal interacts with a service tier comprised of EJB's (there are few web services implemented using stateless EJB's)
We are observing that the old gen becomes full after few hours. Took a heap dump and analyzed using Eclipse MAT.
It reports the following as leak suspects:
Problem Suspect 1
anonymous wrote : One instance of "org.jboss.ejb3.stateless.StatelessContainer" loaded by "org.jboss.mx.loading.UnifiedClassLoader3 @ 0x8c437030" occupies 45,654,248 (11.77%) bytes. The memory is accumulated in one instance of "java.util.LinkedList$Entry" loaded by "<system class loader>".
Problem Suspect 2
anonymous wrote : 277 instances of "org.jboss.ejb3.stateless.StatelessBeanContext", loaded by "org.jboss.mx.loading.UnifiedClassLoader3 @ 0x8c437030" occupy 186,304,176 (48.05%) bytes. These instances are referenced from one instance of "java.util.HashMap$Entry", loaded by "<system class loader>"
anonymous wrote : The problem suspects 1 and 2 may be related, because the reference chains to them have a common beginning.
| org.jboss.remoting.transport.socket.SocketServerInvoker$ServerSocketRefresh @ 0x8c41b908 ServerSocketRefresh Thread
Can someone suggest how to proceed ahead with this?
