Problem:

I started my system as usual but my docker-desktop doesn't work, WSL doesn't respond to commands and there is a process called "Vmmem" using 25% of my memory. I have tried a bunch of thing but nothing seems to work.

System Attributes:

• Windows 10 Pro (10.0.19045.2486)
• docker: 4.15
• WSL: 1.0.3.0

More context:

Recently I was having trouble with my docker set up. I have one particular container that was "crashing" the docker. It was not throwing any exception but after some event (that I couldn't find out) all the other container where unreachable any attempt to stop/start another container would result on "Error: 500 failed to respond...". When this happens I usually just restart the system and everything works fine, but today it wasn't the case. I restarted and I noticed that I had the "Vmmem" process already running at 25% (it usually just reaches this point at the end of the day), the docker desktop could not start the docker backend and when I tried running wsl -l -v I got no response. I can use some docker commands like docker -v but the docker compose up doesn't work at all.

What I've tried:

• restart the system again (nothing changed, still starting with 25% mem usage)
• deactivating Hyper-V (nothing happened)
• stop/start docker service using net start/stop <service> (it gives a response but didn't solve the problem)
• Uninstall docker-desktop (it crashes before even starting the uninstall process)
• Terminate WSL wsl -t Ubuntu (got no response from wsl)
• Overwrite installation with Docker 4.16 (it gets stuck on "Preparing for update... / Stopping VM and preparing for update")
• Forcefully kill the "Vmmem" (I've got Access denied error)

Edit 1:

I managed to finally install the Docker desktop 4.16 but the problem continues, system starts with 25% Vmmem memory usage and docker desktop is not able to initiate backend.

CodePudding user response：

the process Vmeem It represents the memory and CPU consumed by the combination of all the virtual machines running on your Windows PC, there is a possibility that processes are still running on your PC. I recommend you try to launch these commands from the console:

docker stop $(docker ps -a -q)

docker rm $(docker ps -a -q)

This will stop all containers and delete them. If this doesn't work, I recommend you enter your bios settings and disable virtualization, that way those processes will stop, then you can enable it again and try. I wish you luck and I hope this resolves.

CodePudding user response：

Steps that I did to be able to stop "Vmmem" process and install docker desktop again:

• disable Hyper-V
• disable virtualization (BIOS)
• restart system

to this point the "Vmmem" problem was gone

• uninstall docker desktop
• rm all wsl instances
• enable Hyper-V
• enable hypervisorlaunchtype
• restart system
• enable virtualization (BIOS)
• install wsl Ubuntu instance
• install Docker Desktop

Maybe some steps listed here are redundant but that is what I did. hope it helps if other people is passing through the same problem
