VSCode Remote Container consumes too much RAM when 2 windows are open

[vsimundic]

Type: Performance Issue

When I open a remote container in one window and in other window any other folder or workspace (does not have to be in a remote container), my RAM usage starts spiking up until it's all gone and the PC crashes. When I look in the processes in the System Monitor, I see small 7-8MB docker processes constantly showing up. I tried downgrading the version, rebooting, switching remote containers.

A certain number of docker exec process is needed for Dev Containers to work. Are these accumulating? Which ones? Also check if this is still an issue in the latest version.
