web: Web App boozing to much RAM

I have a Xojo Web App, compiled on macOS 10.13 for Windows 64 Bit.

The app “boozing” all RAM it can get. The server has 16 gb of ram, and the app takes 15 and more.

There “Implicit Instance” are all off. So I have no clue, whats going wrong.

Is there a windows command which I can use, to kill the task automatically when the .exe gets 12mb ram?

Because I running as a service, the app will restart, when the task killed - so it would be a possible workaround - until I know why the apps boozing so much ram.
