Hello Railway team,

I am on a trial and haven't deployed or visited my site(s) in over a week, however I got a notification that my credit is now running low. I am confused why my servers are consuming resources when sitting idle (is there no auto-sleep or scale-to-zero?) - I do not have any CRON jobs or background services that would be doing anything. When I look at the logs it shows no activity. I am considering using Railway to bring these projects to production but this is giving me serious pause. When I look at usage (in the attached picture), Memory is the culprit but I am unclear why. Please help me understand what is going on here. Thank you!
