    JMS Consumers stop listening after a period of time.

    Peter Crossley Newbie

      I have been working with JBoss for awhile and we have an application that listens to multipule queues and topics that exist on a remote jboss server. We are not using MDM, the application is running JBoss Server Version 3.2.5. The applications receives the messages just fine for a period of time (Random, I have not seen a pattern).

      After turning the JMS Trace on the server that has the Queues and Topics I found the following (Lets call this server the 'Master' server) :

      This is what the TRACE looks like when it is working on the Master server.

      Then at one point it just stops, the threads on the Remote server are in a wait state and nothing happens or the thread dies and this exception occurs.
      If/When the thread dies this exception is thrown.

      org.jboss.mq.SpyJMSException: Cannot create a ConnectionReceiver; - nested throwable: (java.lang.NullPointerException)
       at org.jboss.mq.Connection.receive(Connection.java:961)
       at org.jboss.mq.SpyMessageConsumer.receive(SpyMessageConsumer.java:289)
      
      ... my internal code ...
      


      This is the Master server TRACE when the remote server consumers stop or die. This continues until the remote server is restarted.

      Any help here would be great, I can get any addtional information that anyone needs to help assist with this problem.

      Thanks you,
