It might also be a problem with the nic (if nics can overheat), because the computing task involes a lot of network traffic and I do see transmitting errors. The computing task (building a debian-live CD-image in a directory that is accessed via NFS over SSH) dynamically creates new processes, so it's not easy to know which process should be paused with kill -STOP Anyway, writing a bash script for that is much easier for me than writing a kernel module.
