Where are the ZeroMQ (ZMQ) messages going (when successful)? The errors are
definitely coming from ZeroMQ.Do you get any messages received on the other
end of the message queue when this happens? It sounds like ZMQ isn't fully
initialized or ready to send & receive at that point in your code. My small
amount of experience with ZMQ found it to be relatively easy to set up and
use. I'd suggest checking whatever is on the other end of the line.
