  • 1.  Message Listener Service WebSphere v7.0 problem

    Posted 01/30/12 03:34 AM
    I have three application servers in cluster v7.0.0.17. On servers I have deployed MDBs. Every server in cluster have one Listener Port and all ports watch same queue (queue is defined in cluster scope). Also every application server have server scope created his own Queue Manager (WebSphere MQ).

    Problem description:
    In one moment third app. server has stopped to receive and process messages, in fact messages has started to accumulate on queue for that app. server. I thought that the listener is stopped, but the console is showing the status of 'Started'. The application server system logs did not record any error. After Listener Port is restarted app. server has starteded to receive and process messages.

    Is there anyone with similar problems ? Is there a solution for this problem?

    Did you checked if that particulat JVM is working by checking any app mapped to it?
    If there are no logs written around that time, please check under FFDC if there are any incidents and also check under profiles directory to see, if there are any dumps [java/thread/heap]. These things will tell us if the server is hung at the time of the incident.
