Periodically I get this error on the produciton: NameError: uninitialized constant CartoDB::Settings

[deemkey]

cartodb-rb-client (0.4.3)
Rails 3.0.9
ruby-1.9.3-p327
nginx/1.4.2

Periodically falls at this code
CartoDB::Init.start YAML.load_file(Rails.root.join('config/cartodb_config.yml'))

So when I start the server the cartodb init works fine, I can change tables, etc
But sometime later it can just fall at that string with the error above, no server restart made, just happens from time to time

I had to use monkey-patching and set the Settings to {}
