For what it's worth, I previously had similar behaviour.

It turned out it was against the host's AUP (I hadn't spotted it in there), and when they detected it they automatically shut the system off (it was an OpenVZ slice so fairly easy for them to monitor).

Is there a way to reduce the CPU usage? Or should I upgrade the server?
