I don't have that process while running WSL2 in my machine. I have vm-agent and vm-agent-daemon, but I'm using a virtual desktop, so this might or not be related to WSL2. Both of these processes consume less than 10 Mb combined. In my other comment [0] I referenced a link from Microsoft that says RAM is dynamically allocated and reclaimed when freed.
