  ****************************************************************
  An application has requested the queue manager to commit or
  backout a unit of work. While this is in progress, RRS is
  terminated and restarted. When RRS is restarted, a
  synchronization process is initiated to find and select units of
  work that were active when RRS was cancelled. Some of these
  units of work need to go to the deferred end of task (DEOT)
  process for termination and cleanup.
  
  RRS synchronization (CSQ3RRSR) can select and queue units of
  work for DEOT while they are still active in the queue manager.
  This results in units of work being terminated and cleaned up
  while still in use.
  

Problem conclusion

• RRS synchronization (CSQ3RRSR) has been changed to check and
  wait for the units of work to be inactive before queuing them
  for deferred end of task processing.
