rare, maybe. But I guess that many erlang nodes are not running in root
privileges and the goal of using a virtual machine should to be
independant of any OS constraints ...

I don't have this behaviour with -sname in my test environment.
(this is also the strange thing because 'localhost' is not fully
qualifed ...)
But I suppose the use of -name is depending of the distribution between
subnets in different datacenters. I can't change this without knowing
what I do and without customer agreement.
This could be a workaround in some case, maybe I can see at changing the
event manager to ignore this kind of message at SASL level,
but a bit weird...

thanks for your interest.
