CHEKC_NE ERROR for the available port

[YangjieZhou]

Hi,

I meet a problem as followed

van.cc:291: Check failed: (my_node_.port) != (-1) bind failed

the sin_port should be equal to -1. Can anyone answer what can cause it? waiting online!!

Thank you very much!!

Could you double check if the port is available? Linux reserves the port for a (few?) minutes even after you kill the process, to identify previous stale connections to that port.

Did you check if you can change the port number and bind ?

I got the same problem here, seems it was a zmq problem, don't know how to fix.

I also encountered it and finally solved it by changing the port from 8000 to another one.
