From the stack trace it has something to do with the setpriority function, earlyoom has a flag -p to increase it's priority, from the man page:

-p Increase earlyoom’s priority: set niceness of earlyoom to -20 and oom_score_adj to -100.

When earlyoom is run through its default systemd service, the -p switch doesn’t work. To achieve the same effect, enter the following three lines into sudo systemctl edit earlyoom:

[Service] OOMScoreAdjust=-100 Nice=-20

My config in /etc/sysconfig/earlyoom had -p:

EARLYOOM_ARGS="-r 0 -M 524288 -s 10 -n -p --avoid '(^|/)(systemd|Xorg|X|Xwayland|xdm|sddm|kdm|gdm|lightdm|plasmashell|kwin_wayland|kwin_x11|ssh|yast|yast2|y2controlcenter|zypper|rpm|dnf)$' --prefer '(^|/)(java|Isolated\ Web\ Co|Web\ Content|WebExtensions|firefox|chrome|opera|falkon|ffmpeg|vlc|mpv|akregator|thumbnail.so)$'"

After removing the -p flag the service starts and since the systemd service config already contains the niceness and OOM score adjustments I guess this flag isn't really needed. -- You are receiving this mail because: You are on the CC list for the bug.
