    ****************************************************************
    * PROBLEM DESCRIPTION: After DB2 command -CANCEL THREAD is     *
    *                      issued to cancel a thread associated to *
    *                      a MQ DB2 service task, abend            *
    *                      6C6-00E50070 is generated without dump. *
    *                      The abend is recorded in LOGREC when    *
    *                      the queue manager is stopped.           *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    During queue manager shutdown when DB2 service tasks are stopped
    there are unexpected reason codes received after the task is
    disconnected from DB2 indicating that the thread has already
    been disconnected by DB2 "-CANCEL THREAD" command. MQ does not
    handle this condition and does not set the state of the service
    task as disconnected causing abend 6C6-00E50070 when the service
    task is forced to terminate instead of a normal shutdown.
    

Problem conclusion

  • MQ DB2 service tasks are set with the correct disconnected state
    when they have been cancelled by DB2 commands.
