  ****************************************************************
  PFA issued false exception for PFA_PRIVATE_STORAGE_EXHAUSTION
  check when model and compare processing occurring
  concurrently and compare completed before modeling.  This
  resulted in issuance of AIRH224I (no data) message when there
  was data and modeling was successful.
  

Problem conclusion

• Code has been changed to eliminate timing window between
  compare and modeling for PFA's PFA_PRIVATE_STORAGE_EXHAUSTION
  check.
