Freebsd 6-Stable lockups
Hi all, I have a kind of anoying problem at the moment. 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 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: Freebsd 6-Stable lockups
Hi Chris, I've noticed the same on three of my FreeBSD 6 systems, until now I haven't found any clue on this. FreeBSD 5 stable was no problem, FreeBSD 6 is quite a mess with no trace at all on what might have caused the machine to freeze. I agree with you that it could very well be a user application problem because my kernel config is quite trivial, my updating routines (cvsup and portupgrade) are trivial and actually the whole configuration of my box isn't exciting. I've opened a thread at bsdforums.org and posted an email on this mailing list as well. http://www.freebsdforums.com/forums/showthread.php?t=38765. http://lists.freebsd.org/pipermail/freebsd-stable/2006-October/ 030225.html Perhaps, comparing both configurations could identify the bad application.

Re: Freebsd 6-Stable lockups
thecommentsabout old hardware are interesting as all my kit is at least 4 years old. Its a bit hit and miss though I have3 systems on 6-stable, only one has the problem. These are the basic specs of the systems. system 1 - one that freezes this is the current hardware x2 intel 550 p3 intel 440GX chipset 2 x 512meg ECC pc133 ram, 1 x 128 meg ECC ram fxp and xl0 old hardware that also freezes was x2 p3 1 ghz severworks chipset(asus CUSL2-LS) 2 x 512meg ECC fxp and xl0 system 2 AMD athlon tbird 700 amd 750 irongate 256 meg ddr ep and xl system 3 2x450 intel p3 slot cpu intel 440bx 1x 512, 1 x 128 xl, dc, and sis all machines are using pata drives looking at the specs, bith the flakey boxes are runniung ecc ram is anyone having these issues who isnt running ecc ram? - Original Message - From: Paul Beckers [EMAIL PROTECTED] To: chris scott [EMAIL PROTECTED] Cc: freebsd-questions@freebsd.org Sent: Wednesday, November 01, 2006 6:21 PM Subject: Re: Freebsd 6-Stable lockups Hi Chris, I've noticed the same on three of my FreeBSD 6 systems, until now I haven't found any clue on this.
