[zeromq-dev] ZMQ Proxy crash in every 3 days

[Francesco]

Hi Ashok,

Not sure what you mean with "crash" in a Python context, however, if this
can help somehow, here's my experience with ZMQ proxy: in my company we're
running it 24/7 for months without issues. There are some differences
though:
a) we use libzmq C API from a C/C++ software
b) the proxy is of type XSUB/XPUB like yours but the transport for frontend
socket is "inproc"
c) we use zmq_proxy_steerable()

As I said this is probably not helping much but the message is: I have
experience with the proxy running in all sort of corner conditions (mute
state on some socket, all queues full, etc) and never found any issue so far
