Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server running JMS2.0 applications with     *
    *                  IBM MQ as the messaging provider            *
    ****************************************************************
    * PROBLEM DESCRIPTION: open handles to MQ queues build up      *
    *                      when the queues are used by JMS2.0      *
    *                      applications in WebSphere Application   *
    *                      Server                                  *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When a JMS2.0 application is running within WebSphere
    Application Server V9, using IBM MQ as the messaging provider,
    the number of open input or output count of the queues used by
    the application can build up. If the application closes the
    JMSContext objects it uses but does not explicitly close any
    consumer or producer objects, then the handles to the
    underlying queues can remain open.
