For segmented  strings  ROW_COUNT  cannot  exceed  COMMIT_EVERY,
  setting ROW_COUNT equal to COMMIT_EVERY value of <num>.

  Explanation:  Data containing segmented strings cannot be loaded
  if  the  value  specified for ROW_COUNT or the default ROW_COUNT
  value exceeds the value specified for  COMMIT_EVERY.   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  specify a value of ROW_COUNT that is equal to or
  less than the value of COMMIT_EVERY.
