I am running stress tests on Stateful EJB with JBoss 3.2.8 SP1 snd testing memory cnsumption using JProbe. JBoss runs out of Memory after 10 hours. ( 128 MB min and 512 MB max)

Has anybody seen something similar ?


The objects with high counts are

org.jboss.ejb.StatefulSessionEnterpriseContext

org.jboss.util.id.UID
org.jboss.invocation.InvokerInterceptor
org.jboss.ejb. StatefulSessionEnterpriseContext$StatefulSessionContextImpl
org.jboss.resource.connectionmanager.CachedConnectionManager$KeyConnectionAssociation
org.jboss.proxy.ClientContainer
org.jboss.proxy.ejb.StatefulSessionInterceptor
org.jboss.invocation.InvocationContext
org.jboss.proxy.SecurityInterceptor
org.jboss.proxy.TransactionInterceptor
