Error description

• We have now seen 4 PMR's (different customers) where after
  MMC.EXE terminates abnormally, Domino tasks will not unload.  A
  frequent example is nchronos as it runs hourly and never exits,
  resulting in numerous concurrent nchronos tasks.  This is
  occurring on Win64 and Domino 853FP3.
