Without seeing your code it's very difficult to say much about what you've done right or wrong. As a complete guess, the error you're getting says it's from zmq_ctx_create. You shouldn't be attempting to (re)create a context while your application is already running - a context should be created only once on application initialization, and only destroyed on application termination. You use that one context for the duration of your application. If you're trying to call create context when one already...

Hi Martijn. Apologies for the noise, it seems like the application had in fact changed from our previously working configuration after all. Somehow the requester connection type in our testing vi had been set to REP as opposed to DEALER. I didn't pick it up as I didn't realise REP:DEALER wouldn't work - I expected that provided we followed the REP message ordering (send/receive, send/receive) this would be fine, but that seems not to be true. After switching to DEALER:DEALER everything works as expected....

I'm migrating our system that uses LVZMQ to a new computer, but after porting the same code (previously win10, LV2015) to the new machine (win7, LV2018) i'm finding that ZMQ processes that try to use the DEALER connection mode hang, either in send or receive message with timeout. REP/REQ appears to work without problems, but unfortunately our system requires DEALER in order to send and receive asymmetric messages. In my dealer, I currently open and bind to a socket, then loop over a receive with...

hi, Thanks for the script. Right now as the system is up and functional I'd prefer...

OK, well it's not what i'd call a solution, but a workaround. I still don't know...

Hi Martijin, I removed, redownloaded an reinstalled from vipm the zmq library again,...
