I'm experiencing daily lockups on a FreeBSD 6.2 machine thats currently
being used as a gateway for a local church school. I have installed and/or
configured the following services which are running on it right now: Quagga
(only using the Zebra daemon), DHCP (via the isc-dhcp3-server port), BIND,
and PF. Everything runs as expected except for the fact that the machine
will completely freeze (console included) quite often. Its recently gotten
as bad as freezing every 3-5 hours. I don't have any custom cron jobs
running and the only job I see that operates at that frequency is daily
maintenance. Thinking it could be a heat problem originating from sitting
on top of a switch, I put a few blocks under and now it runs a good bit
cooler. Last night, I had the windows open and it never got hotter then
luke warm and I witnessed, first hand, it completely freeze for no apparent
reason. Despite that seemingly pointing to it NOT being a heat problem,
I'll be moving it to a shelf by itself. I will also be swapping out the RAM
in a few hours when I get up there to see if that is the problem, but I
still have a feeling (after reading other similar problems like this) that
that may not be the answer. I have a similar setup running at my home which
uses the exact same motherboard but different RAM and HD. The only
difference on my home router is that I have split horizon DNS setup for my
domain and am using IPFW as opposed to PF. My home router has been rock
solid every since I got it (several months ago) and my email and webserver,
which both run FreeBSD 6.2, have never been down except for extended power
outages. I will update you on how the RAM swap goes, but if there are any
other suggestions you have I would greatly appreciate it.
Lockups are usually hardware related. You should run diagnostics on all
your motherboard, RAM, drives, and NIC's. Check that your system BIOS
settings are correct, and you are not "over-clocking" your CPU or RAM.
I would run the generic kernel if you have a custom kernel.
