Thanks for posting this, good to know what happened. Bit of googling 
shows that this happened to a lot of people.

[I was woken up by  a warbling noise in the early hours, found my 
Backend overheat alarm ( set very conservatively) had started because 
the cpu had been running at 100% on both cores for too long. Mythbackend 
restarts didn't help, killed mysql and rebooted, and then mythbackend 
wouldn't start because it couldn't connect to database. Ended up 
shutting it all down for the first time in months :-(, too sleepy to 
fault find.

Thought this morning would be filled with pain, but found that the 
network interface had changed on reboot, and that was all that was wrong 
with database access :-). ]
