This is really a three pronged question: 1. Do we have a project FAQ? 2. Where is it? on daisy? 3. Should we put this as a new entry?
Someone on the users list asked about problems scaling Cocoon--Tomcat was crashing with OutOfMemoryErrors even though plenty of RAM was made available using the -Xmx.... parameter. We pointed him to JVM and garbage collection as a possible culprit (as well as pool sizing). As it turns out, the JVM parameters were the issue. With proper tuning of the JVM (and an upgrade) they have been happily stable ever since. It didn't really have anything to do with pool sizing.
The thing is that this issue is not a Cocoon issue, but a JVM configuration issue. Nevertheless it is not intuitive, and pointers to how to configure the JVM would help others in his situation.
