I'm having difficult with an application deployed in a JBoss 5.0.1 cluster using JBoss messaging. After a period of time, we run out of heap and everything falls over. Using Eclipse Memory Analyzer, I've tracked the leak down to a surfeit of JBossObjectMessage objects, which appear to still be attached to the Topics they were posted to. Looking in the JMX console, these topics have large numbers of messages, seemingly all the messages ever posted.
The application uses NON_PERSISTENT messages and non-durable subscriptions, so I would have expected these messages to disappear from the topics on delivery. The second symptom I've noticed is that there is a much larger number of subscriptions on each topic than I would expect. This seems to increase when one of the clients logs a JBoss Messaging server failure detected - waiting for failover to complete message. This failover occurs randomly, even though both nodes in the cluster are up, and never to all subscriptions on a given client. Further, it seems that once this failover has occurred, any further subscriptions to that topic are not cleaned up on client exit. The JBM configuration we are using is that shipped with JBoss, but with MSSQL for persistence. Sorry for the long post. Any thoughts or ideas are much appreciated!
