There is the corresponding issue in the bugtracker which is already fixed.

Let me know if theres specific info you need to help me narrow the problem down.
Anyone have any ideas?
I had a rel/env.sh.eex file that was setting
export RELEASE_DISTRIBUTION=name
export RELEASE_NODE=api#${POD_IP}
where POD_IP was not set, causing the error.
You should check your pc's os hostname. It should contain ".",otherwise long name can't be used.
When running an EUnit test that tests an application or starts and stops (or tests killing of) gen_server or supervisor processs, error logger outputs crash reports and other messages by default:

How can I avoid these expected messages during testing?
These can be avoided by temporarily disabling TTY reports in the error logger. Surround the code which produces the reports with this:
my_test() ->
error_logger:tty(false),
try
% code that produces error logger reports
after
error_logger:tty(true)
end.
If you use this many times in the tests, this wrapper can be useful:
without_error_logger(Fun) ->
error_logger:tty(false),
try
Fun()
after
error_logger:tty(true)
end.
Which is used like so:
without_error_logger(fun() ->
% code that produces error logger reports
end)
One of the RabbitMQ nodes went down but remained in hung state which didn't let the other node to become active node. Have a VIP through which applications connect to Rabbit, in case one of the nodes go down the VIP switches to the other node but this didn't happen as the first node, that went down, hung itself.
Below are the logs from that time.

RabbitMQ 3.6.6, Erlang 19.1
RabbitMQ is running on Microsoft Windows Web Server 2008 R2 6.1.7601 Service Pack 1 Build 7601 64bit.
RabbitMQ started to crash yesterday after running OK about one year. Now I have upgraded Erlang and RabbitMQ Server to the versions mentioned above but this did not change anything - still crashing
frequently.
