  FPA Reload function can hang or cause some pointer errors when
  one thread subtask processes multiple areas that have the PCL
  pointers.
  Because the initialization of the internal work areas after
  processing one area is insufficient, this problem can occur.
  

Problem conclusion

• The module HFPKARI0 has been modified to clear the internal work
  areas for new area process.
