Error description

  • In WebSphere Application Server v8.5.5, when a JVM hosting the
    messaging engine is terminated, the messaging engine failsover
    to the next JVM in the messaging cluster but it takes a very
    long time to get started and the following exception is logged
    in the SystemOut.log:
    CWSID0032W: An inconsistency in the WCCM document
    sib-engines.xml was detected, for the message point XXX

    ****************************************************************
    Changes in application server suvch as deleting SIB
    destination points cause change processing events to be sent
    through the system.
    There was an incorrect assumption in the
    code as to the order in which such an update event would be
    processed between the list of destination points and the list
    of localizations possibly associated with those destinations
    points.
    This incorrect assumption led to this change
    processing ending prematurely, which subsequently leads to
    CWSID0032W warning messages appearing in the SystemOut.log
    once the messaging engine is stopped and restarted, due to the
    mismatch in these two lists at this point:
