Hi All, I set HWM to 100, hence, at my understanding, once reaching this number, zmq_send() should fail (return -1) but it does not. It just keeps running.
This is per documentation: "If the message cannot be queued on the *socket*, the *zmq_send()* function shall fail with *errno* set to EAGAIN." Note, that I am using "ipc" not tcp, as tcp has its own buffer. Could you take a look at the code to see what's going on, please. This is the financial application, where I want to set the HWM to just one or two. This is if the SUB is busy then PUB should start dropping messages as I do not want to have stale data. I am running Debian with "Current 0MQ version is 4.2.5" https://pastebin.com/p8DU9nQJ Thanks!
