Thanks for that info. The answer to this question seems pretty indefinite. I'm now logging 'free' to a file once per minute so I can see how real-world traffic affects overall memory usage. Still I would need to see the system with processed forked all the way to MaxClients to know how close it gets to OOM. - Grant
