[zeromq-dev] Messages stop processing on ROUTER socket (pyzmq)

[orzodk]

I have a router socket that is collecting messages and sending them to a
pool of dealer sockets (via a different router socket) to do something
based on the message.  In the past few days the app that is the router
socket stops receiving message including heartbeats and just
freezes. When this happens memory usage starts growing until we restart
the process.

The only thing that I can think of that changed is there are many many
more messages. Could this "do nothing", eat memory be caused by hitting
a limit in connections?

In the mean time I'm going to ensure that .disconnect() is called to see
if that remedies the situation.
