Also, obviously, make sure that you're not getting any power surges or anything of the sort; basically anything hardware-related that could possibly cause a reboot.

If you're plugged into a UPS, make sure that the load on it is not too high. -- Bosko Milekic bmilekic@unixdaemons.com bmilekic@FreeBSD.org
