There's some discussion of this in the Guide. There are a lot of ways things can go wrong: http://zguide.zeromq.org/page:all#toc64 Most of these are rare enough. What's more common is slow subscribers, leading to queue overflows in the publisher, or dropped messages, if you set a HWM in the publisher. If you write fast subscribers, or your message rate is low enough to process safely, and if you don't have any failures in processes, operating systems, or networks, then pub sub will be reliable. -Pieter _______________________________________________ zeromq-dev mailing list [email protected] http://lists.zeromq.org/mailman/listinfo/zeromq-dev
