if I enable adaptive sampling the RAM usage goes from about 20GB to 105GB

Adaptive and progressive sampling need to store more data all the time and so it's expected that they use more memory. Furthermore, toon is memory hungry (lots of data is stored per pixel). These two combined I'm not surprised it's using up so much memory.

Reducing your max AA would be my recommendation. Smaller bucket size also seems to help in my testing.
