Qlik Sense Engine health check showing saturated: true even if RAM and CPU are available

[Andrea_Bertazzo]

The Engine health check can show saturated: true even if there is sufficient RAM and CPU available on the machine. 

An example of when this issue can occur is the following chain of events:

1. Two ore more apps are opened in short order.
2. The apps consume all available memory
3. The apps are closed when saturated:true is reached
4. The memory is successfully unloaded, but the healthcheck remains on saturated=true

Environment

Hi @Andrea_Bertazzo , how can I check that? we are experimenting some performance issues but RAM looks to be fine arounf 72% most of the time. I am wondering if that's because of the Min RAM setting in the engine or something related to what is described here?

Thanks!
