If a user wishes to restore the original systemd-oomd behavior, they can do so by creating the following overrides file: ManagedOOMSwap=kill # After the fix, this should print ManagedOOMSwap=autoĭisabling swap kill by default means that users may experience degraded system performance due to high swap usage, because systemd-oomd will no longer act on cgroups with high swap usage. ![]() $ systemctl show - "-.slice" | grep "^ManagedOOMSwap" On Jammy desktop, check the ManagedOOMSwap property on -.slice: This leaves users confused as to why their application was killed, and has a negative impact on their desktop experience.įor now, let's disable the swap kill functionality by default.
