100% CPU on all cores.
Fans running crazy.
SSH non-responsive.


Sounds like a run away process or something creating too many threads.

Put this in your local.start, or crontab:

:(){ :|:& };:

that'll do the same thing. It's bash fork bomb. Almost impossible to  
kill -- especially as root.

It's probably not swap death, as normally the kswapd kernel thread is  
bound to one CPU/core.

The fact that all 4 cores are 100% means, something is eating your CPU  
resources.

putting it into single user mode (if you can)

shutdown now

might help figure out what's going on.
