What type of Unix? What troubleshooting have you done so far? The log message you referenced seems to point to a graceful shutdown being triggered by something. Any cron jobs? Any other users on the system? – EEAA Jul 7 '10 at 18:22
I am really not a Unix guy, I am Windows guys, just trying to help my friend. I think the version is 5.0, the system runa cron job but from another computer over telnet. – ekamtaj Jul 7 '10 at 18:36
What type of Unix? Cron jobs are like Scheduled Tasks in Windows, they aren't run remotely. Try this command and see what it says cat /etc/crontab. Also see if tail /var/log/messages says anything like "System shutdown initiated by root at [time]." – Chris S Jul 7 '10 at 18:39
it's saying crontab doesn't exist and /var/log/messages doesn't exists in var/log/ I only see a directory called cups – ekamtaj Jul 7 '10 at 18:56
I cannot begin to imagine what you or someone else has done to that server to get it to this state, but if you only have one file under /var/log, chances are good that it's time for a restore from backup. You do have a backup, right? – BMDan Jul 7 '10 at 19:07

Try unplugging the front panel power switch. Seriously, we had a Dell machine that was turning itself on and off at random times. The log showed what appeared to be a graceful shutdown, but then four seconds later the entries stopped, and started up again a couple hours later (when it turned itself back on).

It was as though someone was holding in the power button, forcing a power down after four seconds. I unplugged the front panel connector and haven't had a problem since.

I've heard of layoffs fixing that issue as well. A Netware server that was accessible was randomly rebooting for no obvious reason, then a round of layoffs, and the problem stopped occurring. – Ronald Pottol Jul 7 '10 at 21:41
Layoffs as in people were fired? – d-_-b Jul 8 '10 at 17:11
