You most certainly have an issue in your codec, and when it throws an
exception, the connection will be closed.
You can most certainly get some mor einformation by implementing the
exceptionCaught event in your IoHandler (on both the server and the client).
One thing you can also do is to check your encoder/decoder in isolation,
to be sure it works well.
