Help to debug Openbsd freezes...
Hi Gurus, I'm facing a strange and frustrating problem... I run a box with OpenBSD without problem for a while (>2 years). It's still running 3.5 (ok, ok, don't shoot, it's an old one but upgrades are not easy). It's an i386 1U in a safe environment (colo) See attached dmesg below. For two weeks now, the box freezes randomly... No ping, no activity, capslock/keyboard don't work, no error on the console. The only solution is the "magic-button" :( I tested the disks: ok I replaced memory modules: ok (+memtest) I replaced two fans (for disk cooling) No new software has been installed not upgraded. If I check the symon logs, nothing special appends before the "freeze" Any advice?

How old is the box itself? Could be a power supply getting flaky. Without problems for so long, then suddenly this I would lean toward a hardware problem (does not mean its definitely that).

I used to use two realtek network interfaces wich I suspected causing the problems. I replaced those two rl nics and everything went back to normal. System is running ok.

That's exactly one of the main reasons why I have started using OpenBSD at our Institute. Twice a year I spend ~ 2 hours (that includes reading the documentation, testing and coffee break) to upgrade 7 machines.

As another poster already mentioned: upgrades are an easy and well documented process. Do your specific circumstances (e.g. problems to physically access your co-located machines) make upgrades painful? If so, you should probably solve that problem. If you can't perform routine work such as upgrades, what do you do when an emergency pops up? For two weeks now, the box freezes randomly... I've encountered such trouble as well. Several times, replacing the power supply did the trick. You may want to keep those around at the data centre. Cheers, Rogier -- If you don't know where you're going, any road will get you there.
