Error description

  • An access violation exception may be encountered by a runmqchi
    process and the following FDC generated when the queue manager
    is in an ending state:
    
    Probe Id          :- XC130031
    Component         :- xehExceptionHandler
    
    MQM Function Stack
    riiInitiator
    riiTriggerMessage
    rriGetChannelDef
    lpiSPIKernel
    ziiSPIKernel
    xcsFFST
    
    The Trace History present in the FDC will show the following
    sequence of function calls:
    { riiTriggerMessage
    -{ rriGetChannelDef
    --{ lpiSPIKernel
    ---{ ziiSPIKernel
    ----{ ziiSendReceiveAgent
    ----} ziiSendReceiveAgent rc=lrcE_Q_MGR_STOPPING
    ----{ xcsFFST
    
    The trace history shows that the access violation occurred
    when the queue manager was in an ending state.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of WebSphere MQ V6 and V7 (fix pack 7.0.0.2 and
    below).
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    The runmqchi process reads the trigger messages present on
    SYSTEM.CHANNEL.INITQ and tries to start the respective
    channels. Once it reads the trigger message, it inquires the
    respective channel definitions before actually starting the
    channels. During this step, it sends an inquire request to the
    agent process.
    
    If the queue manager is in an ending state during this timing
    window, then the agent process returns a "MQRC_Q_MGR_STOPPING"
    reply message to the runmqchi process. Once runmqchi process
    gets this reply message, it tries to access some data which is
    beyond the reply message buffer resulting in an access
    violation.
    

Problem conclusion

  • A check has been added for reason code "MQRC_Q_MGR_STOPPING"
    before trying to access the reply message buffer, which prevents
    the access violation.
