  • Closed as program error.

Error description

  • WebSphere MQ V7.0.1.10 includes the APAR IV16597 which added
    additional diagnostic logic to generate diagnostic Failure Data
    Capture (FDC) files with Probe ID JO215002 if the client
    determined delays in obtaining an internal lock required to
    send data to the queue manager.
    
    In certain scenarios, it was possible for this new logic to
    generate a diagnostic FDC files once every second, leading to
    an excessive number of files created.

    ****************************************************************
    PROBLEM SUMMARY:
    Following the introduction of the diagnostic code added under
    APAR IV16597 it was found that diagnostic FDC files with probe
    ID JO215002 were being generated more frequently than
    necessary.
    

Problem conclusion

  • The diagnostic code has now been enhanced to wait and only
    create these diagnostic FDC files once every 30 seconds by
    default.
