websocket-rails + redis + phusion passenger: eventmachine not initialized: evma_connect_to_server

[deepsystm]

Hi to all!
I'm using rails 4.2.4, websocket-rails 0.7.0 and redis-rails 4.0.0.
In development mode all works well,
but in production when i try to read Rails.cache i getting
eventmachine not initialized: evma_connect_to_server

I spend many hours to deep dive into this issue, but I can't get it work. Anybody solve this error?
