RE: Memory Use Creeping Up In Steady-State

I was mistaken--the increase is actually about 1-2KB/s. I arrive at
this by "eyeballing" the graph (which is updated once a second). Still
seems rather high, though.

I'm not sure I understand your question, Yoav. When I say
steady-state, I mean that Tomcat is running, all applications have
initialized and no requests are being sent.

Thanks,
