Question

I would like a ‘system’ that monitors a process and would kill said process if:

• the process exceeds some memory requirements
• the process does not respond to a message from the ‘system’ in some period of time

I assume this ‘system’ could be something as simple as a monitoring process? A code example of how this could be done would be useful. I am of course not averse to a completely different solution to this problem.

Answer 1

For the first requirement, you might want to look into either using ulimit, or tweaking the kernel OOM-killer settings on your system.

Monitoring daemons exist for this sort of thing as well. God is a recent example.
