    Question Server Reboots Every Few Days...

    I am troubleshooting what I suspect is a hardware problem (hence why I've posted in the Hardware section). I have a server that is several years old, and over the past few months I have noticed that it is periodically rebooting on its own.

    It is just a home server for my personal use, and I'm not home that much recently due to college and work anyway, but it's becoming a problem because instead of every few weeks, it's started to reboot every few days. It seems to occur at odd times of day when the server is sitting idle.

    I decided to dive into the syslogs and see if I could find out why.

    I've pinpointed one of the time periods when a random reboot occurred. January 26th, 2013 at 4:59am. I do have overnight jobs scheduled, but they're just rsync backups, and I would think they would have been finished by then.

    Code:
    Jan 26 04:17:01 Scimitar CRON[23167]: (root) CMD (   cd / && run-parts --report /etc/cron.hourly)
    Jan 26 04:59:12 Scimitar kernel: imklog 5.8.6, log source = /proc/kmsg started.
    Jan 26 04:59:12 Scimitar rsyslogd: [origin software="rsyslogd" swVersion="5.8.6" x-pid="1384" x-info="http://www.rsyslog.com"] start

    Jan 26 04:59:12 Scimitar kernel: [    0.000000] Initializing cgroup subsys cpu
    Jan 26 04:59:12 Scimitar kernel: [    0.000000] Linux version 3.2.0-36-generic (buildd@allspice) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #57-Ubuntu SMP Tue Jan 8 21:44:52 UTC 2013 (Ubuntu 3.2.0-36.57-generic 3.2.35)
    It looks like there is no syslog information that is relevant whatsoever... it's as if the plug was just pulled.

    It is not a problem with the power source, as the server is on a UPS, and shares that UPS with a wireless access point that has been operational for 33 days.

    What sort of hardware issue should I be looking for here?

    This specific type of problem makes me suspicious of the power supply. I would assume if I had a motherboard, CPU, or RAM issue that I would most likely be seeing a kernel panic or some other type of error before the server offs itself?

    I would appreciate any input you folks have.

    Thanks!

    I went ahead and ordered a new power supply for it. It had a rather specific power supply before as it has 8 SATA hard drives.

    I paid over $100 for the power supply 4 or 5 years ago.... it has since survived a direct lightning strike that blew out other appliances on the same circuit.

    I would be very understanding if it had decided to start failing now, 2 years after being hit by lightning as it's turning 5 years old.

    I looked it up on NewEgg, and felt fortunate to see that they're still selling it, and for about what I paid for it years ago. Also had a $30 promo code and $20 mail in rebate, so I felt like it was worth it. If it doesn't fix the problem, I'll use it for something else.

    I'll let you know how it goes once the new unit is installed.
