It seems that 797MB is used for caching... thats a high number. Anyway to set a lower cache size?

I've read about the /proc/sys/vm/buffermem but my /proc doesn't have it.

Kernel: 2.4.22

I don't see the problem? Linux uses unused memory as cache and unless you have processes using more memory then thats free you dont have a problem, this is all dynamic and nothing to worry about.
