  • Closed as program error.

Error description

  • A queue manager that is a member of a cluster is suspended and
    at some point later is resumed.
    
    At the point the queue manager is resumed an access violation
    occurs in the cluster repository manager process (amqrrmfa), and
    the queue manager can no longer be restarted.
    
    An FDC with the following information is generated at each queue
    manager start attempt, similar to the following:
    Probe Id     :- XC130031
    Component    :- xehExceptionHandler
    Process Name :- amqrrmfa.exe
    Probe Description :- AMQ6109: An internal WebSphere MQ error has
    occurred.

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of clustering wishing to suspend and resume queue managers
    from the cluster.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    Some inconsistent data was not being handled by the cluster
    repository manager process, meaning that the first four bytes of
    a queue manager name were being treated as a pointer. When the
    pointer was accessed it caused the cluster repository manager to
    crash. Upon restart of the queue manager the cluster repository
    manager processed the data in the same way.
    

Problem conclusion

  • The inconsistent data is now being corrected by the cluster
    repository manager so that the queue manager name is not being
    treated as a pointer.
