Hi,

I am having a MDB listen to a broker of a SonicMQ Queue v6.1. JBOSS 4.2.1 EA. For certain adhoc cases the messages are not getting removed from the Queue after being processed by onMessage() method. The same message keeps processing repeatedly. Changing the log level to TRACE I could find the following important clue.

The trace for one that dint repeat:

07/08/08 10:34:07 JMS SessionPool Worker-0 TRACE - org.jboss.jms.asf.StdServerSession.onMessage - Commiting the JMS transaction
07/08/08 10:34:07 JMS SessionPool Worker-0 TRACE - org.jboss.jms.asf.StdServerSession.onMessage - onMessage done
07/08/08 10:34:07 JMS SessionPool Worker-0 TRACE - org.jboss.jms.asf.StdServerSession.run - recycling...
07/08/08 10:34:07 JMS SessionPool Worker-0 TRACE - org.jboss.jms.asf.StdServerSessionPool.recycle - recycled server session: org.jboss.jms.asf.StdServerSession@23cd23cd
07/08/08 10:34:07 JMS SessionPool Worker-0 TRACE - org.jboss.jms.asf.StdServerSession.run - finished run

The trace for one that did repeat:

07/08/08 14:13:30 JMS SessionPool Worker-0 TRACE - org.jboss.jms.asf.StdServerSession.onMessage - org.jboss.jms.asf.StdServerSession@16a916a9transaction already ended

07/08/08 12:05:04 JMS SessionPool Worker-1 TRACE - org.jboss.jms.asf.StdServerSession.onMessage - onMessage running (pool, session, xaSession, useLocalTX): , , null, false

Can someone help me find the root cause. This seems a challanging one to me.

Thanks,
Milo.
