You can write multiple times, and it generates more than one messageReceived
events.

Another issue is that messages may be received in parts (due to network

My suggestion is to use DemuxingProtocolCodecFactory. SumUp example
demonstrates this codec.

If your codec is simple enough, you could use CumulativeProtocolDecoder,
too.
