  * RECOMMENDATION:                                              *
  ****************************************************************
  After previous insyncpoint work to a local private queue, a
  subsequent non-syncpoint put of a persistent message to a topic,
  with a defined subscription to a shared queue, will result in
  the UOWSTDA showing an incorrect date. This is due to the
  pub/sub work resulting in a nested unit of work being created,
  during the processing to put the message. Flags that suppress
  UOW messages in the RALE for the nested UOW are cleared, but not
  set again later. This results in the DISPLAY CONN command
  processing miscalculating the UOWSTDA value in this case.
  

Problem conclusion

• Nested UOW processing has been updated to reset the suppress
  flags in this case, to ensure UOWSTDA is displayed correctly
  in the results of DISPLAY CONN commands.
