The client cannot receive messages after running for a period of time

[huangxc0930]

Hi.
I'm using DEALER mode of jeromq version 0.5.3. After connecting to the server, the client can send and receive data normally. But after running for a period of time, the client cannot receive data, and the "inproc://reqmonitor"monitor do not have any disconnected event.
When receive data, i use socket.recv(0) api.

Looking forward to your reply.
