Version 8.5 Refresh Pack 6 for the IBM Business Process Manager products
Version 8.5.0 Fix Pack 2 for the IBM Business Process Manager products

APAR status

• Closed as program error.

Error description

• The Snapshot Cleanup feature in IBM Process Center can cause
  some DB rows to incor-rectly be removed for named snapshots that
    were initially created in the timeframe of the cleaned up
  snapshots. This is specific to the cleanup of snapshots with the
   scheduled cleanup task and not the WSADMIN command.
  
  
  This can lead to errors similar to this one:

  It can  also cause other errors that may occur due to missing
  records in database tables.
  
  The snapshots affected by this  issue will have  sequence
  numbers that fall in the range of one of the cleanup actions.
