Hello,

Hoping that someone can help me. My server:
Dual Zeon 2.8ghz, 2GB RAM, RAID 0,1, FreeBSD 6.1 RELEASE, Directadmin v1.27.2 is randomly rebooting. Sometimes it happens every other day, sometimes every 2 weeks. When it first started happening every other day I thought that it was FrontPage Ext. as two times in a row it was running when it crashed/rebooted. But I disabled that and still happening.

Most recently is just happened. Could find nothing in the logs, and I happened to be running a top when it crashed and nothing major:

SpamAssasin? I do have SpamBlocker and SpamAssassin running (Still getting blasted with spam, can't wait for SpamBlocker 3)

Any help would be greatly appreciated!

THanks,

Hey Mike,


We just started experiencing the VERY same symptoms, We run FreeBSD 6.1
and 2 weeks ago the machine started randomly rebooting with nothing in the logs. I'm starting to think something may be causing the kernel to panic and the machine reboot.. i havent ruled out hardware but the machine was recently checked for hardware errors and also had the motherboard replaced as we had other issues with FreeBSD 6.0 randomly locking up.. so we upgraded to 6.1 and the problem was solved.. now 8 months later we're getting this rebooting problem.

It's only happened twice to the machine we have running DA and both times were early 06/01/2007 5:50AM and then again 14/01/2007 6:14 AM.

The machine is running FreeBSD 6.1 P6, it's a Dell PowerEdge 2550
Dual P3 1.3 Ghz, 2GB Memory, 4 x 36GB Raid5.

Let me know if you find any new leads, i'm going to probably post to freebsd-questions@ aswell.

Rob.

Same here.

Upgraded to 6.2 and for now everything seems to be fine.

Hi Namesniper,

How often were your reboots, and over what period of time? How long have you been running 6.2?

Any issues with 6.2?

BTW Thanks for the reply!

Thanks,

mike

I have noticed first random reboot yesterday and upgraded to 6.2 almost immediately.

Why not not try to upgrade to 6.2 ?

interesting. i have the same issue. not sure why. /var/log/messages says nothing as to why it rebooted. it led me to believe the datacenter had power issues (which they admitted once).
did your log files say anything to why it rebooted? how did you upgrade to 6.2? cvsup the source & make world?

If your experiencing random reboots take a very good look at the cron jobs you are running. I solved the problem by disabling cron jobs for all users and only running properly configured crons as many users run cron jobs that are very messy.
To check weather this could be the reason take a look at /var/log/cron there may not be errors but the system may crash at the exact point when a certain cron is ran.

Hope this helps some people

the bizarre thing with this one though, i found another thread on here which says how to email details of all cronjobs on all users to an address. ran that, and there's no cron jobs other than one that's aside from default. and the one that's not default only runs at midnight. these reboots can happen at any time of the day, what appears to have absolutely no pattern whatsoever. it'd been 50+ days once before it rebooted, and before that it failed to stay up longer than 2 weeks. same again now. utterly confused, and dc admins are clueless. (or at least, either they know what's doing it and aren't telling me, or aren't bothering to look at it in great detail, which makes them useless anyway)

More then likely it is bad hardware. Ask for a full hardware swap.
