I tried the approach you suggested, to no avail (but I may have done it wrong).
Long story short : the "client" connects a PUSH socket and the "server" binds a
PULL socket. The client then pushes messages.
When everything gets stuck, I observed that restarting either the server or the
client re-establishes the flow. I tried to do this on the client (only):
socket = zmq_socket(zmq_ctx, ZMQ_PUSH);
int heartbeat_interval = 1000; // milliseconds
int heartbeat_timeout = 5000; // milliseconds
zmq_setsockopt(socket, ZMQ_HEARTBEAT_IVL, &heartbeat_interval,
sizeof(heartbeat_interval));
zmq_setsockopt(socket, ZMQ_HEARTBEAT_TIMEOUT, &heartbeat_timeout,
sizeof(heartbeat_timeout));
zmq_connect(socket, address);
and then:
zmq_send(socket, &msg, sizeof(msg), ZMQ_DONTWAIT);
But alas! The server still stops receiving messages at some point. Should I also
setup Heartbeating on the server?
Thanks,
