FreeBSD crashes very often

I'm bit new to FreeBSD, I have used Linux and now I have FreeBSD powered server. I have set up firewall and all other web services to it that I need and everything works perfectly.... almost. FreeBSD reboots suddenly about every 3 day. I don't understand why it is doing that. I don't even actually know where should I start looking the problem. I have checked log files but I have seen nothing special in them. At boot it says that / has not been dismounted properly and my database has gone upside down because these reboots. I don't want to change back to Linux because everything else works so perfectly.

My FreeBSD version is 4.9
Here is my Sysinfo.

I had once FreeBSD 4.9 (or was it 4.8) rebooting spontaneously. Still don't know what the trouble was, except I noticed that the partition for root filesystem was getting pretty crowded. I re-installed and gave the root filesystem twice the amount of space than I did in the first installation. After that the reboots stopped. Dunno what the problem was and what fixed it -- the re-installation or making the root partition bigger.

Thanks for you're answer Dead Parrot. My root file system doesn't look very crowded and I don't want to re-install whole system. I'd still like to hear some more opinions what could cause this and if I don't find solution maybe I have to try re-install (or maybe try some of new technology releases).

Could this be hardware issue?

Post your dmesg. Does it crash while you are running xwindows? What programs are you running at the time of the crash. Are you using nvidia-drivers with nvidia-agp? etc...

Looks like your 3COM card is having some errors. Is that an (E)ISA card? If you don't need that second card, I'd remove it. If you do need 2 NICs, I'd consider replacing the ep(4) card with a PCI NIC, fxp(4) (Intel Pro/100) are generally considered to be very good cards.

Do your logs say anything about a panic? It sounds like you might be experiencing kernel panics.

I'm running in non-graphical mode. I'm running only some services like Apache and MySQL for my own minimal use.

Here's my dmesg:

That 3COM looks a bit strange but it has worked with Linux but it has always given errors. I can try to change another card to that computer and see if it helps. I have also downloaded FreeBSD 5.1. Log files don't seem to contain anything related to crash.

I installed FreeBSD 5.1 and changed network card to another for testing... I can't yet say whether it reboots itself or but but there seems to be a lot of errors in sysinfo now: sysinfo...

Whoa, that is a *lot* of errors. I should have mentioned that Realtek-based cards are generally not recommended (poor quality), but still there shouldn't be *that* many... did you properly configure each card on a separate subnet?

ifconfig gives me this:

Hmm, no inet4 IP on the second card then? Are you using it for anything? If not, shut it down (or remove it?).

I take it the box hasn't crashed yet, right?

It is for pppoe connection.

And no, the box hasn't crashed yet but last time it was up for 3 days and then crashed.

EDIT:
I changed old card back and see if it works but it seems that there is already one error. I just don't understand what is going on.

I had similiar such issues with various network cards ( Specifically a Realtek8139 and a 3Com ). I bought a Intel Etherexpress PRo 10/100.

While they are pricy, they work. I've had that card in one of my servers for four years now, never had a single problem with it and maintained uptimes over a year.

I'd dish out the cash for a good card, and I know FreeBSD works excelent with the Intel card.
