Unreal consumes all RAM when monitors power down

Development Getting Started & Setup

I am new to Unreal, falling out from Unity as I am sure most new people are. I have a strange problem where my monitors power off when I go to bed. When I wake up, Unreal has consumed all RAM. After quite some time of the monitors being back on, RAM eventually releases. I was able to capture both states with screenshots.

Anyone have an idea of what is going on here?

I’m on 5.0.3 and it happen aswell, sometimes even after 10 minutes idling, but i have several DefaulEngine.ini scattered in many folders, and i don’t know wich one to pick, since none have a rendering section.
