Comment 2 David Hill 2018-07-18 02:03:21 UTC
epmd did start properly:

rabbitmq   17972  0.0  0.0  48856   516 ?        S    00:11   0:00 /usr/lib64/erlang/erts-7.3.1.4/bin/epmd -daemon


So it's not totally the same issue as this BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1310808 


But might be solved by updating erlang to 19... or any other solution that you deem valid .

I didn't test this with RHOSP 12 but that setting is also available in RHOSP 12.  It'll probably break there too.

Looks like it's a duplicate of a bug 1590602. In short we assume that at least ::1 is up and ready.
