acceptCount="200" just means that the socket will accept 200 clients /in
addition/ to those currently being served by RequestProcessor threads.
The only way to "see" those waiting clients would be to query the socket
itself (maybe only available at the C-library level?).

Your configuration allows for 500 request processors, so seeing only 200
doesn't seem too bad. I agree with Mark's confusion over your
configuration: you seem to be trying to use both a standard connector as
well as an executer. You should pick one and stick with it.
