Please note recommended version of zeromq library in your wiki

As I can see, dcell works with old version
http://download.zeromq.org/zeromq-3.2.5.tar.gz

And does not work with new versions. The known bugs of:

1. Assertion failed: check () (src/msg.cpp:248)
2. undefined method `[]' for #<DCell::Registry::RedisAdapter
   does not fixed there.

But 3.2.5 still works. It cost me hour of debugging :)
Thank you!

This is an underlying ffi-rzmq issue, but that is changing. Will double check that situation and note the status of that.

I am watching this issue also. Thanks for mentioning that version 3.2.5 works.

For those having issues with OSX, and using BREW, you can install the ZMQ 3.2.5 by:
$ brew tap homebrew/versions
$ brew install zeromq32
$ gem install ffi-rzmq

Afaik this has been resolved in the latest ffi-rzmq-core(1.0.4).

👍 To having docs here, I spent yesterday debugging this (if only I had thought to check the issues, doh). Was using ffi-rzmq-core 1.0.4 and getting the same error.

Actually overhauled my whole environment a few times, what fixed it was the zmq version.
