man oomd.conf: > SwapUsedLimit= > Sets the limit for memory and swap usage on the system before systemd-oomd will take action. If the fraction of memory used and the fraction of swap used on the system are both more than what is defined here, systemd- oomd will act on eligible > descendant control groups with swap usage greater than 5% of total swap, starting from the ones with the highest swap usage. Why memory usage doesn't count? Bug or intentional?
