+ # 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.
