  .
  The analysis from the dump shown the 5C6-00F30457
  abend issued by CSQ3TM00.
  The problem occurs when an RRS batch application
  (in this case the broker) publishes a message to a topic
  which has PersistentMsgDelivery set to MQDLV_ALL.
  A nested unit of work is started and the puts of the
  publication messages are performed in-syncpoint.
  This results in ACEANPC being set by CSQIRRSI.
  When all of the publications have been put successfully,
  the next unit of work is committed.
  However, ACEANPC is not reset. When RRS is restarted it
  will try and clean-up all of the RRS batch ACEs.
  As  part of this processing CSQ3TM00 is invoked, and
  invokes CSQ3CT80 for thread termination, indicating that
  normal termination should take place as there is no
  inflight unit of work.
  However, CSQ3CT80 detects that ACEANPC is set, although
  it has been invoked for normal termination and therefore
  fails the request with reason code 00F30093.
  CSQ3TM00 detects the failure and the 5C6-00F30457 abend
  is issued, resulting in the queue-manager abending with
  reason code 00F30420.

  ****************************************************************
  When an RRS application publishes a message to a topic out of
  syncpoint, an internal nested uow is created if the message
  delivery option (NPMSGDLV/PMSGDLV) requires messages to be
  successfully delivered to all (or all durable) subscribers, or
  if the publication uses MQPMO_RETAIN option.
  When the publication is delivered to the subscriber queues, the
  context ACE is flagged as no longer being at a point of
  consistency (ACEANPC = on).
  After the publication completes, the internal uow is committed
  however ACEANPC is not cleared.
  
  When RRS is restarted CSQ3RRSR resyncs with RRS and drives
  the context ACE through EOT processing.
  The ACE is incorrectly flagged as not being at a point of
  consistency, leading to the reported abend and queue manager
  termination.
  

Problem conclusion

• CSQINTOP is changed to reset ACEANPC when an internal uow is
  committed and returns the ACE to a point of consistency.
