Yeah, I knew what the select/poll calls are, but I will look at decreasing the number of threads to a more suitable number. Are these threads bound to a specific connection or is it a thread pool that gets requests delegated to it from the open connections?

It's easy to start monitoring right before the event when the leading edge to leading edge time is exactly 5 minutes! > No, should not be a problem.

Our app doesn't really use a pool in the traditional sense... just one connection bound as a given user for that user's session... but I'm glad to hear that it shouldn't be the problem.
