Line 28 of your example code is wrong. It is not correctly setting a high water mark. It is probably reading garbage because you are getting the string length of the MESSAGE constant and using that as the option length. zmq_setsockopt(intDataSocket, ZMQ_HWM, &messagesToStore, strlen(MESSAGE)); Fix that and try again. cr
