The diagnostic returned (13) indicates that you've asked for records =
out of
the range of the resultSet.  You've asked for records 61-81 and there =
are
only 60 records in the resultSet.  It looks to me like you're paying
attention to the number of records in the resultSet, but it would help =
if
that was in the log.
