A system I run keeps = radomly freezing/locking up. This can be anywhere from 2 hours to a week = after the last reboot/lockup. The only fix its to power cycleit. It isnt = kernel panicing, it just locks. Even accessing via serial doent work. I = have changed all the hardware so the issue is unlikely to be there. The = load on the box isnt all that high and the memory usage looks fine (all = rrded). The box is running quite a lot of services (apache, mysql,exim. = spamassasing, clamav, courier, openvpn, zebra). Usually all these = services, apart from openvpn and zebra, run in a jail. I dont think = this is an issue as the machine still freezes if i run them non jailed. = Deactivating all these services apart from openvpn and zebra (needed for = monitoring), seems to fix the problem from what I can see so im fairly = sure the problem lies in these somewhere. However can anoyone suggest I = way i can easily pinpoint the problem other that stepping though each = app, as this would take an age to perform and be very tedious. The system has been rebuilt from src (make world) several times, and I = have dont a portupgrade -a. All the local installations were done from = ports. I have tried running a debug kernel, but it didnt seem to yeild much = useful info. Im running 6-stable( last build 4 days ago ) its an SMP kernel on 1 gig intels with 1.2gig ram 2 x 80 gig ide hd
