Description felix luk 2023-02-26 10:44:45 UTC
Description of problem:
systemd-oomd keeps killing processes even when I have lots of swap space. I have tried to create an override file 99-oomd-override.conf according to an old Fedora bug report on systemd-oomd, but the override doesn't seem to work.

Version-Release number of selected component (if applicable):
unsure

How reproducible:
Intermittent. systemd-oomd mainly kills Firefox, at least a couple of times a day. It has even killed gnome terminal when I was running $sudo dnf update -y, so now I am circumventing that issue by bring up a real terminal <ctrl>+<alt>+<F3>.

Steps to Reproduce:
1. Running Firefox
2. 
3.

Actual results:
Firefox gets killed at some random interval. 

Expected results:
Firefox keeps running.

If no immediate solution is available it would be nice to have some way to override the default setting in the meantime.

Additional info:
Here is my swap listing:
[ruppie@fedora system]$ swapon -s
Filename				Type		Size		Used	Priority
/dev/zram0                              partition	8049660		476928	100
/dev/sda5                               partition	51199996	0	-2

'rpm -q systemd-oomd-defaults' ?

We removed oomd configuration to monitor swap use in systemd-251.4-38.fc37.
Do you maybe have some left-over configuration that messes this up?
Please attach a log ('journalctl -b') from a boot where the issue reproduces.
We might be able to say more with that.

Created attachment 1950034 [details]
output of journalctl -b

Output of journalctl -b after Firefox crashed today. It's pretty big.

Comment 3 felix luk 2023-03-12 15:04:46 UTC
Output of "rpm -q systemd-oomd-defaults" is:
rpm -q systemd-oomd-defaults

Please note that my system started as Fedora 34 and was upgraded several times to Fedora 37.

This message is a reminder that Fedora Linux 37 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 37 on 2023-12-05.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a

able to fix it before Fedora Linux 37 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.
