listen EADDRNOTAVAIL error in Node.js

Question

I installed Nginx and Node.js in my server.

When I try run my node.js file, I get an error:

node.js:201
        throw e; // process.nextTick error, or \'e         


        

Answer 1

This also will occur while 'ip addr add i:p:v:6' is still in limbo or something (just executed/ing), and the interface is I presume not totally ready to listen and still busy adding the new ipv6 address.

Using an execSync [see https://nodejs.org/api/child_process.html#child_process_child_process_execsync_command_options] to call 'sleep' for a 2 second pause seems to allow listen to not error with Error: listen EADDRNOTAVAIL.

[It's really a bug I think in NodeJS 7.4.0 on Ubuntu because this doesn't happen with ipv4 address creation at the instant before usage/listen connection.]
