Hmm. This is strange. Can you attach a thread-dump?
Also, acceptor threads should not be increased to 200, IMO. Is it the request-processing threads
that you need (most likely, yes). They are configured as following out of the box:
[request-processing header-buffer-length-in-bytes="8192" initial-thread-count="2" request-timeout-in-seconds="30" thread-count="5" thread-increment="1"/]
Can you set the thread-count to 10 and see what happens?
Also, please see:

configure Grizzly to run a load-test.
Thanks,
Kedar
