Load Average skyrocketing

I have a dedicated server running FC4. It's 1.6 Gig hz, 512 meg RAM, 64 bit processor.

I had one site on it then added a new one which is a torrent tracker. The total peers for the torrent tracker are about 400. The server operated flawlessly until the torrent tracker was added.

A few days ago both sites slowed to a total crawl. I asked my host to see what was going on. He restarted apache and told me that the disk was accessing constantly and that a mySQL process was hung.

Last night at about 1:00 am this happened again. I had added munin to my server to help diagnose this. I see the load average which had been running less than 2, spiked to 50. MySQL threads jump from only a few to 250. Netstat, Number of processes and VMstat also see huge spikes when this happens.

The data from Munin is graphed here:

Is there some configurational values of apache and/or mySQL that I can set to stop this?

Any other ideas on how to further troubleshoot and fix this?

Thanks in advance

Is the solution not obvious?

Matt: If the torrent tracker was so unimportant that it can be removed, then why do you suppose would it have been added to the server?
