bug#40116: GDM: Memory leak in .gnome-shell-real process

[sirgazil via Bug reports for GNU Guix]

I can't use GNOME anymore because of the problem I explained in the following thread:

https://lists.gnu.org/archive/html/help-guix/2020-02/msg00206.html

On recent system upgrades, the problem got worse. Before, I could get to the end of the day despite the leak; but now it takes around 3 hours for the .gnome-shell-real process run by the gdm user to eat the remaining RAM.

It seems that the bug is stronger in the GNOME desktop, but I've seen, at least once, .gnome-shell-real using an abnormal amount of RAM while in sway (about 800 MiB).

Ouch.

Could you check if it happens in a VM?  That is, you build your GNOME
config with ‘guix system vm’, try to do some activity in the VM, and
check in top whether ‘gnome-shell’ is growing.

Thanks,
Ludo’.

I can try, but last time I did something like that the VM with GNOME was too slow to do anything (this computer only has 4 GiB of RAM).

That looks like an upstream problem

    https://gitlab.gnome.org/GNOME/gnome-shell/issues/64

are we going to investigate backporting a fix?

I'm also hit by that bug. I do not use gnome though, and the .gnome-session-real process is owned by gdm. Ram usage is at around 200MB when starting and after a few days (putting the laptop to sleep during the night), it got to 2.4GB, even though I don't really need or use it beside logging in. After another restart, it was at 600MB after a day. That memory usage is ridiculous :/

bug#40116: GDM: Memory leak in .gnome-shell-real process

[sirgazil via Bug reports for GNU Guix]

I tried a virtual machine with my system configuration during 4 hours and couldn't reproduce the leak (I used "guix system vm"). ".gnome-shell-real" kept using about 260 MiB of RAM and it actually went down to 220 at some point.

In 4 hours, in my real system, the leak would have been visible.

I'm planning to create another virtual machine with "guix system vm-image" instead to install all the packages I have in my user profile and leave it running overnight to see if there is any difference.

I wasn't able to create the VM image with this method. After an hour, the image was still building. I interrupted the process and gave up.

[sirgazil via Bug reports for GNU Guix]

I experience the same as Julien yesterday in a computer reconfigured with sway (no GNOME), but still using GDM. Here's a screenshot of "top" with gdm's .gnome-shell-real using 2.5 GiB of RAM:

I'm currently trying other other desktop environments in combination with slim login manager to work around the issue.

I've been using a configuration with SLiM and GNOME for more than 20 hours with no leaks.

I've been using GDM again for 8 days now, and I don't see the leak anymore.

What is the status of this old bug [1]?  Especially since the last merge
of core-updates.

At least on my side (I'm sirgazil), the status remains the same: this is not an issue anymore.

I didn't close the issue, though, because I wanted to hear from other people affected by it first.

So, if Julien and Arne, for example, don't experience the issue anymore, I'm happy to close the issue.

Let wait 15 days and if no answer, let assume it is not an issue and
close it. :-)

Thank you for your feedback.

bug#41215: memory leak in gnome-shell

[Arne Babenhauserheide]

I see a memory leak in Gnome Shell 3.32.2

The following is top output after several days of uptime:

  PID USER      PR  NI    VIRT    RES  %CPU  %MEM     ZEIT+ S BEFEHL                                                                                       
  864 gdm       20   0   39,6g   1,1g   0,0   3,5  85:04.12 S  /gnu/store/3r8h4lygzs06jyx89ffi1y2bbda9s76y-gnome-shell-3.32.2/bin/.gnome-shell-real

RES 1.1g is a bit much.

I tried to capture a coredump with gcore -o /tmp/gnome-shell 864, but
that increased the memory usage to 8g RES before I killed gcore.

Best wishes,
Arne
