I'm running 8.04 desktop, with proftpd, Samba, NFS and fail2ban. I had a first-ever crash this afternoon, but I was away and didn't get to the machine until 6 hours later, and remotely then.

I'm trying to figure out what caused the crash, and have been looking through logs in /var/log, but I don't see anything strange. I have another machine running 8.04 server on the same circuit, so I don't think the PC lost power...

Does anyone have any suggestions of where I can look to see what caused the failure?

Thanks!!
