It should be enough to setReadThreadsCount to 5, no need to set actual
ThreadPool, because Grizzly can create its own ThreadPool of given size.
It might be good to see what is the default thread pool size configured
in your server. Can you pls. send your server's jstack dump ($jstack <PID>).
I'd also recommend to use Grizzly 2.3, IMO it is much easier to use. If
you can share your Grizzly related code (you can send it me privately) I
can try to help you migrate it to 2.x.
Thanks.
WBR,
Alexey.
