"find" Keeps Starting, Hogging Resources

Every so often during the day, my hard drive starts grinding non-stop, my processor pegs out and my machine becomes unuseable. The culprit is almost always "find" being run by "nobody". I have to kill the process to make the machine useable again.

I'm sure there's a logical reason for this process loading and doing whatever it is doing. However, I would like it to not do it again. This is a temporary machine (my PC needs repairs) and is not very fast at all. If the hard drive spins, everything else stops.

How do I prevent this? I've looked in crontab and nothing there is responsible for it.

And now I have another program doing exactly the same thing. This one is called "mono" and is started by Beagle.

This bugger not only locked up the whole machine, it kept restarting after I killed it. I had to kill it 6 times before it stopped coming back. Then not five minutes later it was at it again!

I thought I had washed my hands of rude software fighting me for control of my computer when I stopped using Windows. I hope someone can point out how to keep these two programs under control, otherwise I'm going to CHMOD both of them to 0.
