area <str>, page <num>
  line index maps a total length greater than the expected size
  expected less than <num>, found:  <num>

  Explanation:  The sum of the number  of  bytes  of  all  storage
  records  mapped  by  all the entries in the line index is larger
  than expected.  Further  verification  of  the  page,  including
  segment and set occurrence chain verification, is abandoned.

  User Action:  Correct the error with the RMU Restore command  or
  the SQL IMPORT statement and verify the database again.
