  If a logical processor fails to unpark, a variety of error
  conditions including an ABENDSRN005 may result from incorrect
  handling of the unparking failure. Errors may arise when the
  target of the unpark begins to process the unpark request but
  does not complete before a timeout condition occurs. When
  this happens, the target processor may enter an inconsistent
  state, which can lead to a variety of abend conditions or
  other anomalies.
  

Problem conclusion

• Code is added to CP to track a logical processor through the
  various stages of an unpark request. If an error is detected
  during unpark of a logical processor, this additional state
  information is used to determine if the processor can be
  recovered or if CP has lost control of it. When a processor
  can be recovered, the processor state information is corrected
  and normal error recovery will take the processor offline;
  CP will remain running. If the processor cannot be
  recovered, then a new abend, ABENDHIP009, is taken immediately
  for purposes of first failure data capture.
