That looks like the server is dropping the connection, in which case
there really should be something in the server logs. How many "accepted
TCP connection", "starting TCP connection" and "closing TCP connection"
messages do you get for a typical test run? And are there really no
warnings or errors?

It is possible that the server is simply too busy draining messages from
your few hundred publish-as-fast-as-I-can channels.
