Ed. Why don't you set a maximum heap size and see if it garbage collects when it hits that size. Sounds like your application does not need that much memory so try setting it to something like either: JAVA_OPTS=-Xms64m -Xmx128m Or CATALINA_OPTS=-Xms64m -Xmx128m This assumes you are starting Tomcat using the bin/catalina.bat script.
This will start it off with 64MB and let it grow to about 128MB (probably a bit more in reality). It should garbage collect at that point. If you are running Java 1.5 you can use the included Jconsole tool to monitor memory usage. It will show you a saw tooth pattern if the garbage collection is working properly.

At that point it's affecting system performance and I have to reboot. I'm pretty sure the GC would have run in there somewhere. So, yes, the heap is growing, if that is what the task manager sees as Tomcat's memory usage climbing (I think so); it will do so until I run out of memory - I haven't let it get that far, though.

Or is the heap just growing? Garbage collection is a bit arbitrary and may not occur until there is a need.
