Just to let you know about a possibly interesting edge case which *may* be related to this bug - if I use "ipv6.disable=1" to disable ipv6, "export ERL_EPMD_ADDRESS=127.0.0.1" works as expected, if I use "net.ipv6.conf.all.disable_ipv6 = 1" via sysctl to disable ipv6, I get "epmd: failed to bind socket".
Using RabbitMQ 3.5.7-1ubuntu0.16.04.1 on 16.04.
Tried the workaround from comment 6 but obviously that's unlikely to work with ipv6 disabled.
