[rabbitmq-discuss] RabbitMQ clustering with SSL

[ramviv.123 at gmail.com]

We also noticed two other failures.  When we kill the epmd process and 
restart rabbitMQ we see the following error.  

{error_logger,{{2013,8,13},{17,31,53}},"Protocol: ~p: not 
supported~n",["inet_tls"]}

   According to one other thread here, this should go away if we use the 
latest version of erlang, which we are using.  Rabbit MQ also seems to 
recognize the latest version of erlang, when we do rabbitmqctl status. We 
checked this  removing the SSL.configuration.  As mentioned in the ssl 
config guide for erlang, if we uncomment the commented out section of the 
config file below, the RRabbitMQ server would just hang.  I am able to 
connect the WebUI, but I never get the success message on the terminal I 
started the server.  Also, the other node when brought up, times out trying 
to connect to this node.
