Fatal error

Hi,

Last tuesday I upgraded a production DB from 7.1 to 7.2.
Everything seemed fine till saturday, nightly vacuum exited with:

Debut: Sat Aug 31 04:00:01 TAHT 2002
FATAL 2:  open of /var/lib/pgsql/data/pg_clog/0323 failed: No such file 
or directory
server closed the connection unexpectedlyThis probably means the server terminated abnormallybefore or while processing
therequest.
 
connection to server was lost

FATAL 2:  open of /var/lib/pgsql/data/pg_clog/027E failed: No such file 
or directory
server closed the connection unexpectedlyThis probably means the server terminated abnormallybefore or while processing
therequest.

The files actually do not exist.

After "truncating" (not "dropping") the offending table and reloading 
it, the error disappeared.

This is a Linux system, with stock 2.4.18 kernel; no other problem on 
the system (public web server).
/var/lib/pgsql is on its on Reiserfs partition, with plenty of room left.
Database is mainly accessed trough Perl-DBI + DBD-Pg-1.13.
No other component except Postgres and DBD-Pg were updated last week.

Don't know what to do and any help will be welcome. I can also provide 
more specific information if needed.
