Is there any way to start node.js grpc server with tcp ipv4 mode?

[nandychen]

The details is that the node.js grpc server is started as below

server.bind('0.0.0.0:50051',
            grpc.ServerCredentials.createInsecure())

Next, when i check the listen port by netstat -tuln, get below result which shows the port is listened by ipv6(tcp6) mode:

tcp6       0      0 :::50051                :::*                    LISTEN 

Actually, my docker env does not support ipv6 by checking with lsmod |grep ip

Enventually, the server will crash irregularlly and restart later, and generate a coredump file like this:

So, my question is:

1. Is there any way to start server by setting ipv4 or ipv6?

2. Is this coredump file related to ipv6 not supported?
