ZMQ and Active Port Detection app try to bind to the same port

[Omer Anson]

ZMQ and Active Port Detection app try to bind to the same port.

Active Port Detection should detect that a multiproc publisher is already installed and running, and use it for pub/sub.

[Omer Anson (omer-anson)]

Reduced in priority. Workaround: Use etcd with etcd pub/sub, or redis with redis pubsub.

Fix should include removing 'multiproc' pub/sub, and using broker-only pub/sub mechanisms.
