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.
