For  segmented  strings  COMMIT_EVERY  must  be  a  multiple  of
  ROW_COUNT,  setting  ROW_COUNT  equal  to  COMMIT_EVERY value of
  <num>.

  Explanation:  Data containing segmented strings cannot be loaded
  if  the  value  specified for COMMIT_EVERY exceeds the ROW_COUNT
  value and the value specified for COMMIT_EVERY is not a multiple
  of  the ROW_COUNT value.  ROW_COUNT is set equal to the value of
  COMMIT_EVERY and the load continues.

  User Action:  If  the  table  being  loaded  contains  segmented
  string  fields and the value of COMMIT_EVERY is greater than the
  value of ROW_COUNT specify a value for COMMIT_EVERY  that  is  a
  multiple of the value of ROW_COUNT.
