I had a similar issue even when not running X. To be honest, I can't  
say I have a concrete idea of exactly what caused it. I simply became  
security-nuts and began wondering if it wasn't someone just toying  
with me; hardened my sshd config and installed denyhosts to monitor  
failed loggins. This was a month ago and my uptime has been perfect,  
with no restarts.
