[zeromq-dev] How to detect if a remote socket has closed

[David.Briant at ubs.com]

I can't reproduce it reliably.

Are there any logging options I should turn on? I don't really want to use a debug dll cause a) I'm not great at C++ and b) I've no idea how to rebuild python.

David,

Can you reproduce this portably using a simple Python client/server
pair like the examples in http://www.zeromq.org/docs:user-guide#toc4?

If we can reproduce it we can fix it.
