+ # When you're using Passenger with smart-lv2 (default) or smart spawn method,
+ # Resque doesn't recognize that it has been forked and should re-establish
+ # Redis connection. You can see this error message in log:
+ # Redis::InheritedError, Tried to use a connection from a child process
+ # without reconnecting. You need to reconnect to Redis after forking.
+ #
+ # This solution is based on
+ # https://github.com/redis/redis-rb/wiki/redis-rb-on-Phusion-Passenger
