Error description

  • The queue manager ends.
    
    
    An FDC file is written that contains this information:
    
    Probe Id          :- ZC038020
    Component         :- zcpSetInitiator
    Program Name      :- amqzxma0
    Major Error code   :-
    STOP
    Probe Type        :- HALT6109
    
    MQMD Function
    Stack
    ExecCtrlrMain
    zxcProcessMessage
    zxcMQIRequest
    zxcConnectAgent
    zcpSetInitiator
    xcsFFST
    
    The above FDC is generated due to data inconsistency and will
    cause the Queue Manager to end.
    
    This problem is occurring in iSeries , AIX and Linux
    environments.
    
    The problem is extremely rare, and has only ever been seen on
    systems running high workloads.

Problem summary

  • PROBLEM SUMMARY:
    ****************************************************************
    USERS AFFECTED:
    High workload systems may be affected by this issue.
    
    Platforms affected:
    iSeries
    
    ****************************************************************
    PROBLEM SUMMARY:
    The root cause is the possibility of creating a timing window
    when data may be inconsistent, as a result from a Power type
    processor deciding to re-order the instructions when detaching
    a pipe.  The issue historically has been very rare and
    frequency of occurrences very low.
    

Problem conclusion

  • Code has been added to remove these timing windows.
