If you remove the outer loop in the client, and just run the client five or
six times instead, then it will still die. So I'm gonna say that it's the
server dying.

Neither one; they don't exit. They just block forever after a while.

> 3. What version of 0mq is in use?

2.0.10. I'm using the iamaleskey version of lua-zmq. Either of these can be
upgraded if you think that's the problem (a new version of lua-zmq got
announced this morning on the Lua list)

> 4. Can you reproduce the problem on linux or osx?

I don't have the ability to try right now; only have access to a Windows 7
machine. I'll post something about OSX later tonight or tomorrow if I
haven't found a solution then.

That would be cool, but it's the exact opposite of what the ZeroMQ guide

"First, do not try to use the same socket from multiple threads. No, don't
explain why you think this would be excellent fun, just please don't do it."
