  ****************************************************************
  When the calling thread of an autonomous procedure is
  cancelled, the thread that is executing the autonomous
  procedure is expected to abend with a soft cancel ABEND04E
  RC00E50013 abend when the called procedure is finished and
  returned to DSNVEUS2.  If the soft cancel abend happens to
  occur after the calling thread is resumed, DSNVEUS2's recovery
  will attempt to resume the caller again.  This could result in
  the calling thread being resumed prematurely if it happens to
  be suspended waiting for its own updates to complete.
  

Problem conclusion

• DSNVEUS2 has been updated to avoid resuming the calling thread
  twice during recovery.
