PJ, there have been some recent problems discovered in the NIO connector
that cause request processing threads to be lost from the pool, but I
believe all of those were fixed by 6.0.32.

If you post back, please include your <Connector> configuration and tell
us which connector you are intending to use (unless specifically
configured, you can't tell the difference between an AJP and non-AJP
connector, for instance).

Thanks,
