Memory / Freeze / High CPU / OOM Killer known problems & Fedora

Hi.

I would like to start a thread to recap all known problems related to Memory / Freeze / High CPU / OOM Killer known problems with Fedora 40 (I’m using SilverBlue but this should also apply to Workstation). Purpose is to share information with other users but also to highlight it to Fedora Team & Gnome Team for Fedora 41.

Below are issues I’ve identified / more may exist - it would be great to list them all :

juin 02 23:56:59 faithnomore kernel: Out of memory: Killed process 259346 (nautilus) total-vm:5167508kB, anon-rss:201224kB, file-rss:5400kB, shmem-rss:0kB, UID:1000 pgtables:3504kB oom_score_adj:200
juin 02 23:56:57 faithnomore systemd[67575]: dbus-:1.2-org.gnome.Nautilus@4.service: Failed with result 'oom-kill'.
juin 02 23:56:59 faithnomore systemd[67575]: app-gnome-org.mozilla.firefox-480410.scope: Failed with result 'oom-kill'.

I have 32 Gb of RAM and I didn’t expect RAM issues / swap usage with Fedora initially as I just use Firefox (with many tabs, still need to find a good way to suspend unused tabs, Auto Tabs Discard extension does not seem to work well) , VLC, an a few Gnome programs …

From Ask Fedora to The Water Cooler

Added tech-talk and removed f39, f40, gnome, intel, nvidia, silverblue, workstation

Hello @deepspace9 ,
As this post is not actually an ask for help I moved it to the Watercooler Category where discussions of this type belong.

Thanks @jakfrost . Noted for the future :slight_smile:

CPU throttle high usage I see when using diatrobox. at this setup I left it out and use only toolbox and no CPU issues. Can’t say I see any high memory leaks or issues either on my setup not even multiple taps, YouTube on and code ide with blender and still nothing out of normal

Me neither, I have 32Gb Ram and have never oom’ed :face_with_raised_eyebrow:, I would suspect @deepspace9 has potentially something running in the background that is hogging resources, perhaps running top is a good idea when these issues are happening.

Thanks @phatle & @jakfrost for your feedback.
My Firefox is using a lot of memory for sure - I tend to use way too many tabs.

Need to find a good way to move some tabs to Bookmarks.

I use a few extensions :

More extensions more resources.

I tend to use normal bookmarks and close the tabs after done since for me multiple tabs on idllenis just pointless when. You need to go that page you can achieve same just opening the page from bookmarks

Each tab eats memory and if there isint any suspend/idle unused tabs they all eat your resources and then if you stream YouTube it takes again more and then you split GPU on so many places and again more resources then CPU comes to help and that mights explain more on high CPU usage/throttle

BTW the memory and CPU usagebis not even high on provided screenshot pretty normal on hardware acceleration enabled with high demanding websites many images etc shopping sites and youtube

Thanks @phatle .
Firefox is not the one to blame. I got the issue reoccuring (progressive system freezing, then gnome session terminated - systemd OOM service) without Firefox / just using brave with 10 tabs , using vlc a couple of time, and moving files through nautilus.
Hard to find the culprit - plenty of logs. Strange not to see similar complaints (freeze with CPU usage).

i would start htop at boot and monitor it as you go normal work and see what processes uses the memory before OOm-Killed what apps for more details for possible root cause

My approach was to use standard top through :

top -b -cb -d 1.0 -w 512 > cpu-wayland.txt

cpu-wayland.txt : Proton Drive
I can replicate the issue with both Wayland & Xorg using Brave (with 10 tab, 1 youtube/h264), moving 100 videos files with Gnome files, and a vlc triggered from time to time.

kswapd0 seems to go up the roof (strange as I have plenty of RAM , 24gb / sorry not 32gb) and does not go down in most cases.

Seems related to 110501 – kswapd uses 100% of cpu, no swap, no NUMA

PS : for the record, I’m using an Intel Core i5-8400T processor

i basically just tested this similar on my gnome silverblue 40 running 1391 raw pictures from sd card to hard drive with 120 4K videos and i didint get anything to freezing or memory related memory was max 6.7GB in use cache was 38GB and swap 524kB. i had YouTube open with YouTube music and chrome with 13 tabs and i only got small lags when hitting write speed 2 GiB/s on my laptop. CPU usage never got near 10% average was 5%

this came good time since i just got those files to work with so had to run multi tasking and see if something happens

@phatle Thanks a lot for testing. I will check my memory (memtest) and my BIOS setting/firmware. Maybe such parameter is causing the issue.

Not much improvement after Lenovo recent firmware update and Intel Turbo Bost disabling.
Issue is still around when moving 240 files over network through SMB … Weird
