Wow. That is pretty old. I've pretty much forgotten about the 2.4 kernel. There have been a lot of bug fixes since then, but I wouldn't know off the top of my head anything specific that would explain this. > I tried > upgrading to 1.1.11, but had to back down to 1.1.7 as the new utils > refused to do an fsck.

I'm pretty impressed that it's been holding up this long under such a high load.
