Getting hacked and having huge warez files being downloaded from somewhere on your server. This happened to me once, a couple of years ago.
Spammers hacking you or using an exploit of some kind to send mass email. You'd probably know about this by now.
Some kind of DOS attack.
Sometimes badly written spiders just get stuck or confused. I can think of several occasions over the past few years when I was slammed by one spider from one IP address for days. Didn't appear to be malevolent, and is pretty much remedied via the .htaccess file.
...Obviously your log files would go a long way towards explaining what's happening.
