    JBM thread leak?

    Mr. Overlord Newbie

      I'm using JBM 1.4.0.SP3_CP03 to send messages.

      The messages are produced on clustered JBoss AS from a stateless session bean which uses a clustered queue residing on the clustered servers.

      The destination for the messaged are remote MDBs on external non-clustered JBoss AS.

      The MDB reply with a response using a replyTo queue pattern.

      After sending many messages, I'm unable to send any messages at all - it all gets stuck and the only way I know how to get it working again is to restart the servers.

      I was looking at the JMX console on the clustered servers and I noticed all these threads that look like this:

      Thread: jbm-server-session-76-yg80uxif-1-z4lutxif-adsehk-t36hs4 : priority:5, demon:false, threadId:391, threadState:WAITING, lockName:java.lang.Object@931c53
      
       java.lang.Object.wait(Native Method)
       java.lang.Object.wait(Object.java:474)
       EDU.oswego.cs.dl.util.concurrent.LinkedQueue.take(LinkedQueue.java:122)
       EDU.oswego.cs.dl.util.concurrent.QueuedExecutor$RunLoop.run(QueuedExecutor.java:83)
       java.lang.Thread.run(Thread.java:595)
      


      There was no less than 100 of these threads shown in the JMX console when it all got stuck.

      Does that look normal?

      It looks highly suspicious to me.

      Why is it creating so many of these threads?

            Clebert Suconic Master

            You have a thread (Executor) per Session.

            It looks like you're leaking Sessions.


            As you're using Spring Template (from what I see from the other thread),
            http://www.jboss.com/index.html?module=bb&op=viewtopic&t=139492
            this is highly possible.

              Yes, i'm using the Spring JmsTemplate to send a response in an MDB to a remote clustered queue.

              If I move the MDBs into the same clustered servers where the clustered queues reside, I don't get this problem - it only happens when the MDB is running remotely from the clustered queue.

              Strange.

              From everything I read, it should be safe to use the Spring JmsTemplate for what I'm doing since I'm using it to send a reply and I'm using "java:/JmsXA".

              Doesn't the JmsTemplate close sessions?

                You need to look at the JmsTemplate source code, or ask that question to Spring guys. We focus ourselves on the JBoss Messaging implementation which is already enough workload for us ;-)

                  Mr. Overlord Newbie

                  It appears my problems were a Spring bug.

                  I updated my Spring jars from v2.07 to v2.55 and all is well so far with my testing.

                  I think I need a vacation now :)
