Hmm, that does sound weird. Do you have other webapps also deployed
alongside this one? If you reload those webapps, the threads in the
thread pool will be recycled after a webapp undeployment to flush-out
any nasty stuff that might be tied to them. You can try setting the
"threadRenewalDelay" to a negative number to disable this particular
kind of recycling.

You might still be on crack.

Are you observing a performance penalty for this, or are you just
trying to explain an as-yet-unexplained recycling of threads?
