But what can be the reason that 8 TCP worker processes are unable to
be idle enough to serve 16 UACs? The UACs are sending REGISTER and
SUBSCRIBE messages every 5 minutes only, and hardly any INVITES are
being made. It would seem that even a single TCP worker process
should be able to serve the 16 UACs exchanging little traffic no?
