[zeromq-dev] JeroMQ crashes application

[Ivan Pechorin]

> There is a method in the class where 1) the context is retrieved, 2) a
socket created, 3) message published and 4) socket closed.

Socket close command is processed asynchronously by reaper thread, and it
seems like you don't give it enough time to release resources.

Creating/destroying a socket for each message is not a right way to use
ZeroMQ/JeroMQ.
