I have the Repl set configured on ports 27117, 27118 and 27119 locally. I have made sure the repl set configuration is correct in the DB layer, Check below,

[ruby-1.9.3-p286] ~ mongo localhost:27117
MongoDB shell version: 2.0.4
connecting to: localhost:27117/test
PRIMARY> exit
bye

[ruby-1.9.3-p286] ~ mongo localhost:27118
MongoDB shell version: 2.0.4
connecting to: localhost:27118/test
SECONDARY> exit
bye

[ruby-1.9.3-p286] ~ mongo localhost:27119
MongoDB shell version: 2.0.4
connecting to: localhost:27119/test
SECONDARY> exit
bye

This is my config/mongoid.yml file which I have configured as per the docs here.

When I visit the root path of the my application, I get Timeout::Error. Below is my server log,
