Hi, I've been running into some strange behavior with ZeroMQ, and the fact that I couldn't find others with the same problem probably means I'm doing something wrong, so here goes.
First off, the basics. I'm running Windows 7 x64 with libzmq 3.1 beta. I have a PUB-SUB setup (with some multi-part messages) over TCP. Originally I didn't care about properly shutting down the context or sockets and everything seemed to work fine. Then I started noticing that whenever the subscriber program would crash, the publisher would crash as well with the following error message: Assertion failed: !incomplete_in (..\..\..\src\session_base.cpp:209) ... so in the client destructor I added some code to shut down the socket and context at exit. Hooray, now when the client crashes the server stays up! However, the client prints the following during the shutdown procedure: Assertion failed: Successful WSASTARTUP not yet performed (..\..\..\src\signaler.cpp:124) This doesn't make sense to me because data was flowing through the socket, so the socket would have to be started. Similarly, if I add the socket/context shutdown on the publisher side, it prints the following when it crashes: Assertion failed: Network SubSystem is unavailable (..\..\..\src\signaler.cpp:124) These are probably all manifestations of the same mistakes on my part. Any insight would be helpful, and please let me know if there's other information that I should provide. Also, I have a couple of more minor questions. First, I'm considering using PAIR sockets over INPROC for doing inter-thread communication. However for my application latency is really important and I can't afford an unnecessary delay in signalling. What is the overhead of using zmq sockets for this as compared to a standard boost::mutex? Secondly, I tried finding a way to build zeromq statically with my application (so I don't have to use libzmq.dll) but it looks like this is currently unsupported. Has anyone had any success in doing a static build with MSVC 2010? Thanks very much!
