  ****************************************************************
  One of the roles for the expiry processing's expiry tasks is to
  generate a TriggerMessage if applicable if the TriggerInterval
  has expired. However if there is a TriggerMonitor performing a
  MQGET with wait on the initiation queue for the trigger message
  to be put to and the application is terminating during the put ,
  it will attempt to switch to this address space number, however
  this is never restored. This results in a S058 RC3C abend in the
  expiry task.
  
  After the abend in the expiry task, Expiry_Task_count is
  not decremented. This results in the queue manager shutdown
  hanging, waiting for the count to be 0.
  

Problem conclusion

• The processing for a put of the trigger message has been
  updated to switch back to the original address space after the
  processing in this case. This ensures the abend will not occur,
  resulting in the count being correctly decremented.
