Error description

  • When a name resolution error in an intermediary queue manager
    prevents a remote
    MQSC session from communicating with the ultimate target queue
    manager then error
    AMQ8101 is displayed in the MQSC session.  When the MQSC session
    is ended then
    the session crashes with a core dump.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of IBM MQ V8 and V9 who use MQSC to
    administer remote queue managers.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    When a name resolution error in an intermediary queue manager
    prevents a remote MQSC session
    from communicating with the ultimate target queue manager then
    an error message is
    returned to the runmqsc session which displays error AMQ8101.
    
    A programming error during the processing of the error message
    meant that a memory
    buffer pointer was incorrectly reassigned.  This caused the
    memory buffer to be freed twice when
    the session was ended, resulting in a crash and a core dump when
    the runmqsc program exited.
    

Problem conclusion

  • The programming error has been fixed to prevent the pointer
    being incorrectly reassigned.
