Hi, I'm part of the team that worked on the Fedora Change Proposal that enabled systemd-oomd by default: https://fedoraproject.org/wiki/Changes/EnableSystemdOomd Joining this discussion late, apologies - I wasn't subscribed to ubuntu-devel prior to today, but will try to catch up on the thread on the archive online. I had a discussion about the lack of notification before a kill with pabs on the debian-mentors channel recently (while packaging psi-notify for Debian; Ubuntu PPA is here: https://launchpad.net/~michel-slm/+archive/ubuntu/psi-notify) (both psi-notify and systemd-oomd act on the same pressure information, but psi-notify just notifies you when certain thresholds while oomd kills the cgroup that causes most of the memory pressure to try and stop getting to a situation where the kernel does it, and likely pick a worse target).
pabs and I agreed that having an actionable notification prior to the actual kill would be an improvement, even if the process likely to be killed might differ between the notification and the actual kill, and after discussing this with the team, Anita published this RFC last week: https://github.com/systemd/systemd/issues/23606 Given that we have two major distributions now shipping oomd (Fedora and Ubuntu -- strictly in chronological order, not implying any value judgement here), should we discuss any potential tweak / improvement either on the GitHub issue and/or on the systemd-devel mailing list? https://lists.freedesktop.org/mailman/listinfo/systemd-devel It will probably be good to share as much implementation details as possible and get them applied upstream.
