I got a home server setup with Debian 6 which stopped/crashed and stopped responding. It's a headless server with SSH access only.
After waiting for a day I did a hard reboot and the system started working again. Really like to know what caused this?. I am using it without any issues for almost 3 years now.
I checked the syslog and messages logfiles and didn't find anything. Got a cron job which reports the IP address every 5 minutes and according to that it stopped around 8.15am on 17th Feb. The remaining entries are from today.
these are the entries from dmesg, I assume PWRB is for pressing the power button and PWRF for force reboot. Don't know if the entries just before that make any sense. Is there any other place where I can find any information?
