  ****************************************************************
  FABY107A is issued in prefix update process, because HPPR does
  not release exclusive control of CI/BLOCK explicitly.
  When the update of the CI/BLOCK is unnecessary, HPPR removes the
  information of the CI/BLOCK from the buffer control block
  without releasing exclusive control of the CI/BLOCK. So, if the
  CI/BLOCK is read again, exclusive use conflict occurs and HPPR
  issues the message FABY107A.
  When concurrent prefix update is processed, the exclusive use
  conflict may cause timeout in writer of pipe FABYPIPE.#03 and
  HPPR issues the message FABY2004E.
  

Problem conclusion

• HPPR has been modified to release exclusive control of CI/BLOCK
  explicitly when the update of the CI/BLOCK is unnecessary and
  HPPR removes the information of the CI/BLOCK from the buffer
  control block.
