[Rdo-list] rdo-manager hostname issues with rabbitmq

[Mohammed Arafa]

yes so i had the fqdn only in my hosts file and rabbitmq couldnt find the

after i added shortname to my hosts file i definitely passed over that bump
(adn stopped elsewhere). there is a thread about it on this list ...
somewhere :)
