Ah, sorry, my bad. I had switched to Socket in my mind...

Let me clarify (I've been far from MINA for 3 months, and too much in
3.0, so I'm a bit rusty :/)

- NioProcessor do the select(). This is mainly used by the
NioSocketAcceptor, because we may have more than one selector.. For UDP,
it does not make sense, we are using one singe selector.
- Thus, if you want to spread the load on your server, then you have to
do what you have done : add an executor filter in your chain.

So far, regarding your initial question, I think you are doing the right
thing. Now, considering your pb, yu should probably check that the
previous message has been written (thus your handler has received the
messageSent event) before trying to write another message.
