Sleeping node js process?

Question

Node.js

I use paid vds
If the application is not accessed for a long time (more than a day, for example), then it falls asleep and then does not respond to the next requests.
Moreover, the application itself works, but does not send a response to the middlewars. I
use the framework - express 4

Answer 1

Maybe an error occurs, I had this, it stopped when I caught the error.
