The podman process wakes up between 10-20 times per second, per powertop

[federicomenaquintero]

Issue Description

I'm afraid I haven't done my homework to narrow this down, so I just have evidence from powertop(1). The podman process wakes up between 10 and 20 times per second for a container that should be pretty much idle - it's a shell inside a distrobox.

Is it possible that there is a runaway timer, or something?

Thanks for reaching out, @federicomenaquintero.

Is it possible that there is a runaway timer, or something?

Not on the Podman side. Could it be that distrobox is firing Podman in the background for monitoring purposes?

Can you share with arguments the frequent Podman processes are started with?

Here's the distrobox one, sorry for the environment noise:

And here is a smaller one I run by hand; it's from a container image for CI:

podman run --rm -ti --cap-add=SYS_PTRACE -v /home/federico/src/librsvg/main:/srv/project -w /srv/project registry.gitlab.gnome.org/gnome/librsvg/opensuse/tumbleweed:x86_64-1.68.2-2023-05-03.0-main

[vrothberg]

Thanks! If you run it by hand without distrobox, do you still see the issue? I am under the impression distrobox is responsible for the man invocations of podman.
