gnome-shell RAM usage growing in few hours

since the upgrade of gnome-shell 3.34, RAM usage of gnome-shell grow in a few hours ...
I disabled extensions and set Adwaita as GTK theme, but this not solve the problem.

4 Gigs of used RAM is okay, because i expect that preload is active.
may you post the output of 'systemctl status preload' . if it's active the RAM usage is totally normal.

p.s.: with the standard settings of preload it will use always round about 3 GB-Ram to preload the most used applications. there is nothing to worry. if you are running applications that need a lot of RAM just upgrade your RAM-Size. But usually preload is working really fine.

Hi @olli , thanks for your reply.
I don't worry about 4G RAM used by the system but about 1.5G of RAM used by gnome-shell process in only 2h40 of uptime ... if i don't restart gnome-shell, it will grow taking all memory !

 1930  1762 1494224 11:26 00:09:33 /usr/bin/gnome-shell

that's curious. maybe someone else has a idea. i'm not using gnome so i can't give any advice.

Have you tested other kernels?

Rarely your internet driver is the cause of this.

Stop network manager, then rmmod both your network modules. Wait a few hours to see if things have improved.

I tested on Linux 4.9, 4.14, 4.19, 5.3 ...
This is my corporate pc so i will test network modules later in the late afternoon.

Thanks for help.

you may also try
gnome-shell-performance from aur.

what is this package and what kind of changes are on it compared to the extra/gnome-shell ?
can I break something ?
I am not very comfortable using this aur package on my production pc ...

I tried your suggestion, stopped NetworkManager and removed network modules, but the problem remains, gnome-shell growing a lot in a short times ... :face_with_head_bandage:

may you post the output of 'systemctl status preload' or are you kidding ?
if it's active you can deactivate the service and test again.
and for god's sake why do you believe that removing the network manager would solve your problem ? Are you serious ?

WOW man ! Keep calm and go peacefully :crazy_face: !
I don't use preload and i don't removed NetworkManager but stopped it as suggested by tbg, that is a serious and veteran forum member.

thank you, likewise, for your good intentions :smiley:

Dude, I never said anything about removing network manager. I simply said to stop network manager. I certainly was serious because a bug in a network driver has been known to cause ram usage to increase gradually over time.

Rmodding the network modules (while a low percentage chance of being the culprit) is a perfectly valid trouble shooting step. If you'd take a look at my profile you'd realize I've more solves on the forum related to networking issues than any other user.

I know @pacop is an advanced user and therefore was easily capable of following my advice without instructions.

I realize you are also a competent user @olli, however as a newcomer on the forum you should perhaps familiarize yourself with the users that help on the forum regularly. Most users that have hundreds of solves on the forum tend to have a clue of what they speak.

I think being critical of long time forum helpers advice is not a good way to introduce yourself on any forum. Unless someone is giving dangerous advice there is little to be gained by being critical of others only trying to help.


I have dug deeper and deeper, reinstalled all packages of gnome group, checked services and autostart files, analyzed gnome-shell memory leak with heaptrack but finally showing gnome-shell cgroup slice i noticed /usr/bin/appimagelauncherd and /usr/bin/appimagelauncherfs.

systemctl status 1156

Removing manually installed package appimagelauncher fix the memory leak. :sweat_smile:

Nicely done. I knew you were too sharp not to figure out the solution. Good work.
