Sorry that I can’t be more descriptive on this, but the game just had 6,8 GB of memory commited to it.
I believe I am getting a similar problem. This is using way too much memory.
All I remember doing was playing on Harry’s Lobby server and playing a few rounds of Minigolf and one of Virus.
Just closed my game after almost 10 GB were commited. I had spent the last 2 hours in a Lobby non-stop.
