[erlang-bugs] bug: Protocol: "inet_tcp": register/listen error: eaddrinuse while starting a node

[Igor Goryachev]

Hi, everyone!

I have noticed some troubles while starting node with '-kernel
inet_dist_listen_min 5290 inet_dist_listen_max 5290' options. And
everything works fine when these options are omitted. 

The output is here:

Crash dump was written to: erl_crash.dump
Kernel pid terminated (application_controller) ({application_start_failure,kernel,{shutdown,{kernel,start,[normal,[]]}}})
===========


After a little bit of investigation I've noticed, that there is no
'{reuseaddr, true}' socket option in the lib/kernel/src/inet_tcp_dist.erl. If
I add this option, recompile inet_tcp_dist.erl, put it into proper
place, everything works fine like when mentioned above kernel options
are omitted.

The tiny patch is included.
