[Bug 1969248] Re: Systemd-oomd frequently kills applications on 8GB RAM machine

[Sebastien Bacher]

Thank you for your report. There were some improvements that landed to
fix bug #1966381 but you already have that version. The log shows you
are indeed hitting the ram/swap limits from your machine so it might be
the expected behaviour to avoid getting the machine locking up for
minutes

what's the output of 
$ free -h

before you hit the issue?

Title:
  Systemd-oomd frequently kills applications on 8GB RAM machine

Status in systemd package in Ubuntu:
  New

Bug description:
  On a machine with 8GB of RAM, systemd-oomd will frequently kill
  applications. This has been most apparent for me when using Firefox
  with quite a lot of tabs open. This could probably be avoided by being
  more disciplined with the number of tabs in use but shouldn't need to
  be an active consideration for the user. I think this is less of a bug
  with systemd-oomd as it is effectively doing its job when memory is
  low, but rather I think this is more a case of the default amount of
  swap (1GB) not being sufficient if only 8GB of RAM is present.

  Attached output of `journalctl -u systemd-oomd.service` to show the
  frequency of applications being killed
