  * PROBLEM DESCRIPTION:                                         *
  * Summary details in output of DMPMQMSG may incorrectly show   *
  * negative values for messages and bytes read and written,     *
  * when processing a large amount of data from a queue.         *

  * RECOMMENDATION:                                              *
  * N/A                                                          *
  ****************************************************************
  The number of messages and bytes read and written using the
  QLOAD and QUNLOAD features of DMPMQMSG utility may incorrectly
  display negative values, when used with large queues. This is
  due to the values incorrectly being displayed as signed integer
  values, resulting in the behaviour seen.
  

Problem conclusion

• The problem summary output for these fields has been corrected
  to ensure large values are correctly handled, and positive
  values are returned in this case.
