Hello,
I would have to double check BUT I believe this is fixed in later 2.4.x kernels as well. If you don't want to go through the hassle of 2.6 (although it really is a nice kernel) then upgrade to 2.4.26.
Sincerely,
Joshau D. Drake

A sane kernel should drop disk buffers rather than swapping. We heard recently about a bug in some versions of the Linux kernel that cause it to prefer swapping to discarding disk cache, though. It sounds like that's what you're hitting. Look into newer kernels ...
This was a common problem in the linux 2.4 series kernels, but has supposedly been fixed in the 2.6 kernels. Having lots of memory and turning off swap will "fix" the problem in 2.4, but if you run out of real mem, you're hosed.
