What does top report for memory used for cache? If it's zero and
and you're not swapping out, I'd say you've got a big OS
(configuration) problem. Otherwise, there could be some tweaks
needed for network buffers or maybe your apache configuration (my
money's on the former though). MaxClient's max'd out?
