This is my first time working with IPC so far and I have written this script:
#!/usr/bin/python
import zmq
context = zmq.Context()
socket = context.socket(zmq.PAIR)
socket.setsockopt(zmq.RCVTIMEO, 2000)
socket.connect ("ipc:///tmp/something")
socket.send(b"123")
try:
message = socket.recv()
except:
print("DEBUG!")
message = None
When my server script is running ( it simply sends an answer ) everything is working fine.
But when the .recv()-call timeouts ( e.g. because there is no server running ), the script won't terminate after the "DEBUG!"-print and I have to manually stop it using Ctrl+C.
I tried disconnecting and closing the socket, but it doesn't change anything.
When I put the whole script into a function and call it, I get the following error on KeyboardInterrupt:
^CException ignored in: <bound method Context.__del__ of <zmq.sugar.context.Context object at 0x7f16a36d5128>>

I'm running Python 3.6.1 and version 16.0.2 of the PyZMQ module on an Arch Linux.
