CopyCopter with ActiveAdmin gets loads of Timeout Errors.

Question

I am using CopyCopter with ActiveAdmin. I get the following Timeout Errors in the messages and the Admin side moves like molasses. Why is copycopter even being messaged from the ActiveAdmin views? What part of the handshake am I missing?

Copycopter should not be messaged from the views. The client works by forking a process and contacting Copycopter every 300 seconds. That number is configurable in the polling_delay setting:

https://github.com/copycopter/copycopter-ruby-client/blob/master/lib/copycopter_client/configuration.rb

Maybe the logs above look like Copycopter is part of the app's GET requests because Copycopter's output is being mixed into the logs at funny times.

The Timeout::Error I assume is a problem on the copycopter-server side. How is the server being run? Is it on Heroku with one dyno and the app is going to sleep after 20 or 30 seconds of inactivity? That would be my guess since it is occasionally downloading the translations according to the logs:
