ORA-01410: invalid ROWID with a sqlldr?

I have a unix script that runs everynight. It sqlldrs a file into my database. The SQL Load is set up to truncate the table before it loads it. The script blew up last night and I got the following error in my log table

TIME MSG_DATA
--------------- --------------------------
03-MAR-12:18:30 ORA-01410: invalid ROWID


Does anyone have any ideas?

From the docs

"This error is raised when an operation refers to a ROWID in a table for which there is no such row.

The reference to a ROWID may be implicit from a WHERE CURRENT OF clause or directly from a WHERE ROWID=... clause. "

HTH

thanks. I will look into that.
