RUJ file size may not exceed 8,000,000 disk blocks

  Explanation:  The transaction attempted to extend the RUJ file
  size beyond 8 million disk blocks.  This transaction will be
  rolled back (note that due to the size of the RUJ file, the
  rollback operation may take a very long time).

  User Action:  Reduce the number of records being modified by the
  transaction; commit more often or use a BATCH UPDATE
  transaction.
