Review Information in Requirements

[Oglopf]

A discourse came in asking about the 5 minute PUN cleanup they read about in the requirements section:
https://osc.github.io/ood-documentation/latest/requirements.html#hardware-requirements

There's a line that says:
"The Passenger apps that make up the core of OnDemand (that NGINX is configured with), are each killed after a short period (5 minutes) of inactivity from the user"

I'm pretty sure that is not correct, and if it is I've never had my PUN cleaned up after 5 minutes of inactivity so I'd wonder what our setup is. Either way, this needs to be addressed and corrected or ensure it's correct.

"The Passenger apps that make up the core of OnDemand (that NGINX is configured with), are each killed after a short period (5 minutes) of inactivity from the user"

That's correct, it comes from passenger_pool_idle_time in https://osc.github.io/ood-documentation/latest/reference/files/nginx-stage-yml.html

You may be able to tell by the load times. After that 5 minutes, the dashboard will have stopped. You hit the page and Nginx will just boot it up again. You should be able to see messages around the same in /var/log/ondemand-nginx/$USER/error.log about passenger checking to see if there are any apps it should shutdown.
