Note that the ZeroMQ server is not started. No program is listening on port tcp:50000
The zeromq client sends data once per second, the code is as follows:
zmq_fd->client->send(msg, zmq::send_flags::none)
4、The program crashes after running continuously for 1 to 8 hours
What's the actual result? (include assertion message & call stack if applicable)

Issue description
When the zmq server has not been running, the zmq client may crash。
