[zeromq-dev] XREP/XREQ And Inproc . Clean Shutdown

[Antonio Teixeira]

Hello.

I'm using pyzmq to build a small app and connecting it to a backend using
inproc.

So in simple terms :

external socket XXXX:12134 XREP
Internal Backend IPC/XXX XREQ
Internal Worker IPC/XXX REP


And server(s) Using REQ to make requests to the external socket

Now imagine i need to restart the application running the frontend +
backend.
Should i start by kiling the Workers then the devices and then the external
socket ?

Is there are options / best pratices to prevent message lost like :
"Close External Socket , " Drain All the Message Outbound / Inbound inside
the devices and let the workers close ?"

Just trying to avoid letting a remote connection hanging when the server is
rebooting.

Thanks for the help :)
Antonio
