Logs from chef-server would be helpful.

Assuming the problem is RabbitMQ (seems likely), it looks like rabbitmq isn't 
running at all. Try running `rabbitmq-server` in the foreground and see if 
you get any hints. You can try blowing away the RabbitMQ database (usually in 
/var/lib/rabbitmq/mnesia/ ) and reconfiguring rabbit (see this: 
https://github.com/opscode/cookbooks/blob/master/chef-server/recipes/rabbitmq.rb
 ).
