Hello,

Unfortunately we can't tell you why your application is using as much RAM as it is, think of it in terms of a power company, they can tell you how much power you used, but they can't tell you why you used however much power you did.

As for the app not going to sleep, we also can't say for sure, but my hunch is that your application is keeping an active connection open to something, more than likely, your database.

Please see this docs page for more information on app sleeping - https://docs.railway.app/reference/app-sleeping
