description |
Since I installed Ubuntu 22.04, firefox and visual studio code are frequently killed by systemd-oomd (every 2hours).
I have 8 GB memory and never experienced this before the upgrade to Ubuntu 22.04. I thus assume that the claim that there is not enough memory is abusive. Did 64GB of memory become the minimum requirement to run Ubuntu ?
The second problem is that it gives a very bad user experience which is critical for new Ubuntu users.
There should be a warning prior killing apps to give the opportunity to save the app data. There should at least be an apologize and an explanation after killing the app.
The current behavior gives the impression that Ubuntu 22.04 is unreliable and unsafe to use which is a problem for an LTS release that many people might want to use for critical production context.
There might be a configuration problem with systemd-oomd or simply a bogus behavior. I would recommend to disable it or remove it completely until this problem is resolved. This is what I will do for myself because I have work to do. |
[Impact]
The "swap kill" side of systemd-oomd has caused unexpected behavior for desktop users. A user's browser, desktop session, or some other desktop application may be killed by systemd-oomd when SwapUsedLimit is reached, but system performance otherwise appears unaffected. This leaves users confused as to why their application was killed, and has a negative impact on their desktop experience.
For now, let's disable the swap kill functionality by default.
[Test Plan]
On Jammy desktop, check the ManagedOOMSwap property on -.slice:
$ systemctl show -- "-.slice" | grep "^ManagedOOMSwap"
ManagedOOMSwap=kill # After the fix, this should print ManagedOOMSwap=auto
[Where problems could occur]
Disabling 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.
[Other Info]
If a user wishes to restore the original systemd-oomd behavior, they can do so by creating the following overrides file:
$ cat /etc/systemd/system/-.slice.d/10-oomd-root-slice-defaults.conf
[Slice]
ManagedOOMSwap=kill
