I've got a VM running Windows Nano and Docker containers. The Docker containers are all running ASP.NET Core 5 apps. I'm coming across this really weird bug where the VM is running out of memory, and the Task Manager, Process Explorer do not show what is taking up all this memory:

What I'm observing is that when I kill one of the containers, a lot of memory gets returned so it's definitely caused by a Docker container. The question is, how do I go about diagnosing this problem?

I've tried to take a memory dump of the app in the container I killed, but the dump is no larger than 1GB.
