LinuxQuestions.org - Strange overheating problem

Hi linux experts,

I am using ubuntu karmic kola 9.10. The problem i have been having lately is of overheating of my intel core2duo proc,where the temp reaches around 80-90 degrees and the cpu shuts down after a while and the message from the bios is of thermal trip.

Ideally my cpus temp is around 55 deg,the moment when the temp starts to climb and when i run a top command,i see arpwatch taking 100 % of cpu.After googling i came across this.

Code:

https://bugs.launchpad.net/ubuntu/+source/arpwatch/+bug/357462

How can a process which is taking 100 % cpu cause a system to over heat and shutdown in few mins? I have had seen instances where processes taking a lot of cpu but not something like this.
