Autocad 2021 99% Memory Usage

[kali.mailhot]

Hey, is there a way to limit how much RAM Autocad 2021 uses? Right now on certain files Autocad 2021 will freeze up and crash the computer. If I look at task manager while the program has frozen but before the computer has crashed - it will show that Autocad 2021 is using 99% memory. I downloaded and installed the April 26th patch to Autocad 2021 and Windows is on 20H2, the graphic card's drivers are updated as well. 

The computer is a windows 10 machine with 16 GB of RAM and an SSD.

Not seeing anything like that here:
Did you remember to install the 2021.1 update yet?
Is there a 3rd party add-on you have?

What other programs are running on your PC, and does turning them off help?

What are certain files? Are they very big, do they include complex 3D-geometry, ... ? On which files does that happen and on which files not? Can you post such an example file here please and tell us which command is running while that happens? In some cases it can be that AutoCAD needs a lot of (or nearly all available) RAM. But then it (AutoCAD) should not freeze, it will "only" work very slowly.

I do not know any way to do this.
