    *                      connection,                             *
    *                      complicating leak analysis.             *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The logging logic did not check for duplicate allocation stacks,
    so identical stack traces were repeatedly recorded for each
    connection.
    

Problem conclusion

  • The change compares stack traces and groups identical ones,
    logging the stack only once with all matching connections listed
    reducing redundancy and log size.
    
    The fix for this APAR is targeted for inclusion in fix pack
    8.5.5.21 and 9.0.5.9. For more information, see 'Recommended
