Is there any method for th= is. This sort of thing is very difficult to debug. My suggestions would be: - Check for flaky hardware - maybe run memtest86 overnight. - Run one of the following: while sleep 5; do date; vmstat -m; done while sleep 5; do date; netstat -m; done top systat -v 2 on a VTY or a serial console and see when it's dying and what was happening shortly before. - Check if anything unusual (cron jobs or unusual external activity) happens at the time it dies. - You may be able to debug a frozen system via firewire > Or any known bug reports at this release ? I don't recall this particuar problem being reported. That said, you appear to be running a 9 month old -stable - have you considered updating to either 6.2 or a more recent -stable? --=20 Peter Jeremy --2fHTh5uZTiUOsy+g Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFGgWSo/opHv/APuIcRAjTKAJ9FR2JWTm9/KDcmyg78xu6KzTfe2gCcCxYv 8Jn7wE5zQMBNp+Tj2HhL8EM= =z7iV -----END PGP SIGNATURE----- --2fHTh5uZTiUOsy+g--
