    ****************************************************************
    During queue manager shutdown CSQ3RRSP is called to deregister
    the queue manager as a resource manager with RRS. During this
    process active RRS context ACEs are queued for deferred end of
    task processing.
    In rare cases, CSQ3EOTS calls CSQ3TM00 during deferred EOT
    processing for a context ACE at the same as CSQ3RRSM is
    freeing the ACE as part of end context processing. This overlap
    causes CSQ3TM00 to detect an unexpected state and leads to the
    reported abend.
    

Problem conclusion

  • CSQ3RRSP is changed to wait for any RRS exits that are already
    in progress to complete prior to queuing context ACEs for
    deferred EOT processing.
