  ****************************************************************
  Deadlock in CTIRA_INSERT_LOG on failed open request.  When
  the error path is taken on an open request on a file, the
  CTIRA lock request is not released.  This causes threads to
  lock up over time waiting for the release of the lock.
  

Problem conclusion

• Moved the lock release after the error path in the code.
