Zmq official doc mentions that client can connect automaticly to the server after it lost connection to server, but in fact it doesn't work, so I add some code to deal with disconnecting. Now in my project,  I hit a problem like that: in the begining a certain amount of clients(about 20) can connect to the server with zmq_xrep ok and can communication normally, but after that client with zmq_req connect to the server with zmq_xrep, the server close the connection automaticly, I check it with a network packet capture tool named wireshark, why this happens ? I'm confused about how server deal with multiple clients' connection?

That's a lot of code.

I haven't run your code. However, I suspect that you might be reusing ZMQ_IDENTITY values for multiple sockets. Try commenting out the code where you set the socket identity and run your code again.

Also, it would be useful if you included a pastie of the output you see when you run your example.
