Public bug reported: Multiple times over the last two months, I've unlocked my laptop in the morning and multiple programs have been killed. oomd did the killing. "journalctl -b -u systemd-oomd" indicates that the program hogging memory is [email protected]. It is often using 8GB when it is killed.

It wasn't happening 6 months ago. It has been going on at least 2 months. I'm not sure if the problem is tied to screen lock or to a suspended state on my laptop. I think just screen lock, but I'm not positive. I've never had programs die or see high memory usage when I've been using the computer. I have a large external monitor. Dell 32", 3840x2160 It is connected with a Dell USB-C to DisplayPort dongle. The connection to the external monitor isn't great ... it will disconnect and reconnect when I touch the cable.
