Justin, I cannot have a good suggestion how to find out what hogs the memory.
However, I want to mention that with the use of a good reverse proxy server, you will not need to have very many apache instances running, because the proxy server would take care of the slow interaction with the client's browser. I use perlbal and I am happy, but there are other alternatives. During evening, when I get 35 or so object requests per second, I rarely see more than 1-2 instances of apache actually working at any given moment. At the same time, my reverse proxy is talking to perhaps 10-50 clients, but apache does not know. Igor
