Ubuntu Developers Have An Idea For Handling The Over-Eager Systemd OOMD App Killing

[sarmad]

What happens if the user isn't the criminal? Is the user allowed to kill anyone's process?

Why not, aren't we currently allowing a systemd/Canonical engineer to kill anyone's process? Might as well allow someone actually authorized to access the machine.

No notification. Simply hope an admin will say "hey I'm bored let's check if we have OOM". And no, no way to notify either, until there's enough memory the system is pretty much halted.

Aren't we currently simply hoping an admin will say "hey I'm bored let's check if any of my processes have been killed"?

Fair enough, I thought it was meant as a replacement for the eager reclaiming. What happens in the "let it sit" case, tho?

What, specifically, are you referring to as the "let it sit" case?

What ever Idea it is ....it will be implemented by using snap.

And when it kills your favorite app...OH SNAP!!

For those screaming "just buy more RAM": ugh. It's tiresome to read the same dumb crap again and again.

WRT the actual problem, it seems to me it's poorly configured...

Yes, I agree. Newbie computer users should not run Linux.

They should stick to MacOS...or better yet...Windozes

A privileged service, not just any user. It's, for a start, an actor you trust just as much as your kernel to do the task.

If you manage any server, and I do not want to know, I expect you have some kind of heartbeat running. And, further, I expect you configured vital services to restart on their own if they die.

It was suggested that if the user wasn't around or it was a server, the thing just waited and waited.

Huh? I didn't expect that to be the reading of my post, but I guess it's a valid one. I'll clarify: Canonical, most likely, made a lousy default. Noobs should have a decent experience. But that means defaults need to be sane configurations. One that kills the users' browsers when there's no memory pressure is not it.

1. Zram helps a lot.
2. nohang is an alternative, can kill single browser tabs rather than the whole browser.
