Its just message queuing. In the case in OP, the dealer sends, say, 10 messages, which get transmitted to the other party (the router socket) and queued there. If the application controlling the router socket does zmq_recv(), it'll get one of them. If the dealer disconnects, the other 9 are still in the queue on the router socket, available for the app to consumer as it wants. Ian
