    If the abends continue to occur at a high rate, the excessive
    orphaning for work queues in the QUEx cache may result in the
    exhaustion of QUE1 and QUE2 dataspaces.
    .
    Method NLS4 deletes the work queue if a failure occurs for a
    method call, but does not have a local recovery routine to
    delete the queue if an abend occurs.

    ****************************************************************
    When method EYU0NLS4 (NLS4) is called to process a CICS
    statistics record for CPSM, it allocates a work queue to store
    information it collects from the statistics record.  Since NLS4
    does not have a local recovery routine, if an abend occurs in
    NLS4, CPSM handle abend recovery (module EYU9XLRV) will return
    control to NLS4's caller after collecting documentation for the
    abend.  As a result, the queue won't be freed, and resources
    allocated for the queue in the QUE dataspace will be orphaned.
    If the abend occurs often enough, this can lead to the problems
    documented above.
    

Problem conclusion

  • NLS4 has been updated to include a local recovery routine.  As
    a result, EYU9XLRV will return control to the local recovery
    routine after collecting documentation for the abend.  In the
    local recovery routine, NLS4 will free the work queue, issue an
    exception trace with a debug text of "NLS4Abnd" and a trace
    point Id of 26, and return to its caller with a Response of
    EXCEPTION and a Reason of METHOD_FAILED.
