8 mongrels are way too much capacity. Do you need that many ? Mongrels taking 300MB is not unheard of as James said. Are you using loads of libraries or cache in memory ? Moreover counting per mongrel memory is not so easy. If they use shared libraries the memory per process shoots up in the "ps auwx" command but actual memory usage is not that high.

How much decrease in free RAM happen over the course of a day?
