Re: Freebsd - restarting itself - followup
Hardware could still be an issue... It might be a CPU fan going out. That would explain the reboots. CPU overheats and then reboots. If it's been running fine for 4 months, yes, then it's burned in, but the fan (or some other hardware) might have failed in the mean time.

Further thoughts, suggestions? I would seriously suspect my provider at this point. Are they supplying you with AC power straight from the wall, or do you have a UPS of some sort in line between the power source and your server? If you're running straight, you may want to consider getting a UPS that has either SNMP or syslog facility so you can trap out any alarms if/when the AC from the wall fails. Mike -- Michael K.

It is located offsite (naturally) and about 10 days ago it had a random shutdown (did not come back up) followed by a random reboot a couple days later. It had been running 50-60 days previous. The shutdown occurred just after business hours, the reboot at about 4am. I now have the machine emailing me at specific intervals to try to narrow things down. I have a couple ideas for the both of us. One is that maybe the machine is plugged into a faulty power line, something that is borking the current enough to cause reboots. Another is that maybe the PSU is dying prematurely (3mos old for me). I wish us both good luck. -Derrick To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message

Even really good cpu/ps fans in a clean environment will only last a year or so running 24/7. Most just weren't built with this kind of use in mind. I made a habit of checking fans yearly and replacing as needed. However, I've never had box shutdown, only reboot. Did it really shut down, or was it maybe hung on boot wanting a manual fsck or something? If it actually shutdown, and you're not connected to a ups running a shutdown daemon, I would suspect someone did it accidentally or intentionally... Maybe something like "kill 1"? :) I was also never a power supply snob in the past, but I can honestly say now that I will not buy generic p/s anymore. I went thru 2 generic p/s on my home machine before buying the nice $100 antec... I haven't had any problems since... No lockups/reboots/etc. It definitely turned my thinking around.
