When sending messages with zmq 2.1.10 some of the reserved bits (1-6) are set to one instead of zero like the ZMTP/1.0 specs [1] says. The spec says that they MUST be zero. Having the reserved bits set to one will cause compatibility problems when later versions want to set those bits for new features, so I think this is a bug in the zmq library code.
I found this out when working on a zmq protocol dissector [2] for Wireshark. 1. http://rfc.zeromq.org/spec:13 2. https://github.com/Neopallium/lua-zmq/tree/master/ws -- Robert G.
