I think you are dealing with the slow subscriber problem:

Hi, I use pub/sub pattern to deliver events and have noticed that some messages get lost. I make sure that subscriber binds to the socket and waits in recv() before the publisher sends the event. I was able to reproduce this issue when the publisher calls send() immediately after connect(). If there is a 1ms sleep in between two calls the message is received. Sample code is here: https://pastebin.com/TjUtfFgp Is this expected behaviour, bug or am I missing some important socket options? The OS is Ubuntu 18.04 with libzmq5. wbr Tomaz _______________________________________________ zeromq-dev mailing list [email protected] https://lists.zeromq.org/mailman/listinfo/zeromq-dev
