after my faye server startup with command

rackup faye.ru -s thin -E production

What can I do with such error?? What couses it? How can I handle it?

Solution

i found on this page (it's in russian) http://habrahabr.ru/sandbox/45416/

add this to your faye.ru file

Faye::WebSocket.load_adapter('thin')

this made my solution

i hope it helps an thanks for the advice
