Okay, it happened again.
I looked at the boot log and it appears the computer did not reboot. I just logged that user out. It's the generic user I have logged in when I'm not doing anything and don't want to have root logged in.
I don't understand why my user would be logged out. It worries me. After running a W2K server and getting a ton of Stop errors, waking up to my box having rebooted, I'm wary and nervous about it.
That box did end up having a broken fan, and overheated so the CPU and motherboard were damaged. I don't know why it didn't have an auto shut off.
Regardless, is there anything else I can look at that will give me more info as to why my user is getting logged out, and how I could correct this? If it's a process that hangs, how do I find out which? I am nervous that it could be MySQL... for some reason, the MySQL logs are not working... I have to see why. The log files are there, just empty.
