I need some help trouble-shooting the server. It crashes every night at 00:07 and then it restarts. Also some minutes later MySQLd fails and shuts down (without restarting).
This is the output from /usr/bin/last at the time of crash:

I need some help figuring out why the system crashes. Which logs are interesting, commands to run to get some info (like last)?, etc.
It's a FreeBSD 6.1 machine.

Thanks,
 
I figured out the system crashes when I run /usr/sbin/quotaoff -a. Any clue why?
 
I couldn't say why shutting off the quotas crashes the box.
I can say that there is a nightly quotacheck on freebsd in /etc/crontab (quotaoff, quotacheck, quoton)... so comment out that line and restart crond.

(This post does also answer the mail I got from DA).
You said in the mail that if quota is supported by kernel there is no need to run quotacheck?
I have googled a bit about quotacheck and it seems like people doesn't always run quotaoff and quotaon together with the quotacheck command. Maybe I only have to run quotacheck? (that doesn't crash the system).
But again, if quotacheck is not needed for kernels where quota is enabled then maybe I could skip the whole cronjob for quotas (i have enabled quota in the kernel by adding options QUOTA in the kernel config.
 
I have this error on two of my CentOS systems, one got eth0 problem with it right after the IN AAAA", got type "A" errors : eth0: PCI Bus error 8290
it's not happened on 00:07.
no idea what's wrong...
 
This seems like the cron job that running just after midnight too me.

Why dont you show us the output of crontab -l and /etc/crontab
 
Problem is already solved. Well I didn't do much more research because running quotaoff/quotaon isn't needed.
