Scenario: we have a 4 nodes cluster where we deploy a clustered application ( clusterbench-ee10.ear
) containing some stateful EJB named RemoteStatefulSB:
java:global/clusterbench-ee10/clusterbench-ee10-ejb/RemoteStatefulSBImpl!org.jboss.test.clusterbench.ejb.stateful.RemoteStatefulSB java:app/clusterbench-ee10-ejb/RemoteStatefulSBImpl!org.jboss.test.clusterbench.ejb.stateful.RemoteStatefulSB java:module/RemoteStatefulSBImpl!org.jboss.test.clusterbench.ejb.stateful.RemoteStatefulSB java:jboss/exported/clusterbench-ee10/clusterbench-ee10-ejb/RemoteStatefulSBImpl!org.jboss.test.clusterbench.ejb.stateful.RemoteStatefulSB ejb:clusterbench-ee10/clusterbench-ee10-ejb/RemoteStatefulSBImpl!org.jboss.test.clusterbench.ejb.stateful.RemoteStatefulSB?stateful java:global/clusterbench-ee10/clusterbench-ee10-ejb/RemoteStatefulSBImpl java:app/clusterbench-ee10-ejb/RemoteStatefulSBImpl java:module/RemoteStatefulSBImpl
We have a remote EJB client application performing remote invocations on the cluster nodes, using the emote+http protocol:
remote+http://10.0.99.245:8080,remote+http://10.0.99.224:8080,remote+http://10.0.99.222:8080,remote+http://10.0.97.56:8080
The client applications creates 4000 sessions; invocations are repeated every 4 seconds;
Everything works fine if don't restart any node;
As soon as we shut-down and restart EAP on the first node, EAP memory starts to grow:
EAP memory continues to grow:
until, eventually, the process is killed by the OS:
