ZMQ proxy dies without log

[tvoinarovskyi]

Still diagnosting, but forwarder stops after some time. No logs, just stops forwarding. Restarting forwarder resends pending pub-sub calls. Most likely the ZMQ_XSUB side dies.

I have a hunch, that it raises an error here https://github.com/aio-libs/aiozmq/blob/master/aiozmq/cli/proxy.py#L97 and locks without any log at close call here https://github.com/aio-libs/aiozmq/blob/master/aiozmq/cli/proxy.py#L102

If there were python exception it would have been raised (I believe).
Need more details how to reproduce it ("after some time" what "some" exactly is)

You know, like 2 month on production server. Not much. =)
If I run up upon the reason - will add it in more detail.
