[zeromq-dev] Device CPU Utilization

[Jason Sia]

Hi,

I'm using zeromq 2.2.0 version due to some library dependency, I created a
streamer device push pull , for some reason and its intermittent.  The cpu
usage of the device grows to 100% even if the pusher is only inputting at a
slow rate.  I used pyzmq and then also created a version in C++.

Here is my code:

#include <iostream>

#include <stdlib.h>

#include <zmq.hpp>

using namespace std;

zmq::context_t ctx(1);

zmq::socket_t bind_in_sock(ctx, ZMQ_PULL);

zmq::socket_t bind_out_sock(ctx, ZMQ_PUSH);

int main(int argc, const char *argv[]) {

    bind_in_sock.bind("tcp://0.0.0.0:12000");

    bind_out_sock.bind("tcp://0.0.0.0:11001");

    zmq::device(ZMQ_STREAMER, bind_in_sock, bind_out_sock);

    return 0;

}
Is there a known issue about this?

Thanks,
Jason
