  any errors in CICS and MQ logs that indicated the events failed.

  * PROBLEM DESCRIPTION: Missing High Priority Transactional     *
  *                      events.                                 *
  ****************************************************************
  When the EP statistics are being reviewed the number of put
  events may not equal the number of events sent to the adapters.
  This problem is seen when all of the put events happen to be
  high priority asynchronous transactional ones.
  All transactional events with the same correlation factor will
  be emitted when a COMMIT UOW with the same correlation factor is
  received.
  This problem will occur when more than one COMMIT UOW is
  received. All the events for these additional UOWs will be lost.
  This problem was identified by reviewing EP statistics and
  comparing 'Number of Put Events:' with 'No. of asynchronous
  priority events:'.
  

Problem conclusion

• DFHEPEV has been changed to ensure all events for all COMMIT
  UOWs are emitted.
