can you look at the calls trace? and tell us what you see?
 
having profile tomcat a lot the last 2 years, I personally haven't seen tomcat 
increase heap usage with no requests hitting tomcat. If anything, I consistently see 
tomcat4 and 5 maintain flat memory usage under constant load. In the case of no 
requests, it shouldn't be more 40mb of memory.
 
do you have a webapp that does caching and refreshes?

It's almost impossible to have absolutely nothing running. If you have
tomcat running, that's something (e.g. background processing threads
that watch files to detect changes). However, you still shouldn't see
huge jumps in memory if no users are hitting the server.

What are your observation methods and results precisely?
