High Memory usage when starting Docker

Docker Desktop
1

I have installed docker in a fresh Windows Server 2016 VM using PS command:
Install-Package -Name docker -ProviderName DockerMsftProvider -Force
After installation when I start docker service, HNS service will start using 50 % of my RAM. Note that on my first test I had 8GB of RAM assigned to my VM, later I have resized it to have 16GB of RAM and again the HNS service will use 50 % of total memory (only when docker service is started).
Another interesting thing that is happening is that if I stop the docker service the HNS service will keep using 50% of my RAM, only restarting the VM with docker service stopped will the memory be released.

I have created a new VM, this time with Windows Server 2016 Datacenter (previous was Standard), and I am not seeing this problem any more.

Am also facing the same issue. But I have installed docker in a fresh Windows Server 2019 datacenter VM using PS command:
Install-Package -Name docker -ProviderName DockerMsftProvider -Force
After installation when I start docker service, Everything is working fine. But the HNS service will start consuming my RAM each day. At the end of 3 month. Its going out of memory. It is happened 3 times.
only restarting the docker service is releasing the memory. Please suggest me to fix the same.
