[zeromq-dev] Salt ZeroMQ bug on large deployments

[Thomas S Hatch]

Now that Salt is getting deployed in ever larger environments we are
running into what appears to be a ZeroMQ bug:
https://github.com/saltstack/salt/issues/891

The zeromq assertion we are seeing is this:

Assertion failed: new_sndbuf > old_sndbuf (mailbox.cpp:183)

I think it is associated with the discussion found here:
http://comments.gmane.org/gmane.network.zeromq.devel/9887

The sysctl modifications seem to help, but some of our users are still
seeing it, is there anything else that I should be looking out for here?
