Passenger and Nginx :unix:/tmp/passenger.MGo50AR/agents.s/core failed (2: No such file or directory) while connecting to upstream

Question

I'm new to passenger/ Nginx, I have my rails application running at Nginx and passenger. Some time my application stops working and I got these errors at my nginx error.log file:
