The snap-store is using hundreds of MiBs of RAM.

[James]

The snap-store process is intermittently using hundreds of megabytes of RAM. Is this normal? Is there a solution?

Ubuntu 20.04

[giorgi shengelaia (g-shengelaia2001)]

Same here on relatively fresh ubuntu 20.04 install.

[John (john-mg-allen)]

#metoo 400mb currently on a newish ubuntu 20.04 install. It's not even open...just sits in the background sucking down my ram.

[Mike Leonis (mleonis)]

I have also noticed this behavior.

[Shinjan Saha (sahashinjan)]

#MeToo, it happens for me as well. Currently it is taking up 250MB RAM while its not even open

[Lisa Gentsch (polynomendivision)]

Got the same here. snap-store sitting in the background and eating 200MB of RAM

[Manuel Lañas (mlanas)]

#MeToo, since I installed Ubuntu 20.04, snap-store process is taking even more than 300MB

[John (john-mg-allen)]

Just checked again, 475mb. This is getting an absolute joke and isn't on, why have they released ubuntu 20.04 with this RAM sucking monster? Not all of us are devs with 32GB machines, some of us are on laptops with 4GB/8GB and having a program/service doing absolute nothing sat in the background consuming 1/8th of available RAM is just a slap in the face.

[Fabiano Silva (drhtcl)]

Same here, 447Mb on a fresh ubuntu 20.04 install

[Mantas Kriaučiūnas (mantas)]

Snap-store on 20.04 uses more memory than gnome-shell and Xorg - about 30-25% more than original gnome-software 3.36 I just checked by installing with 'apt install gnome-software' !

[gustav (gustavs)]

Same here 352M on ubuntu 200.04 and it is not even open

[Heraldo Madeira (heraldo-madeira)]

Same problem here, 260M, with apparmor errors related to snap-store:

[Manish (manishmaharjan)]

#metoo, It is using 288MB of my RAM memory when it is not even opened, but just running at the background.

[Eduardo Santos (eduardoflsantos)]

+1

255MB of RAM while it's not even open

[Beloin Sena de Farias Rodrigues (beloin)]

Me too almost 400MB

[Doug (stingray74)]

Fresh 20.04 install and mine is between 200 and 400 MB

[Manoj Patel (mpatelpa)]

snap-store is 430MB

[Zbynek (ybznek)]

Same problem on Xubuntu 20.04, using 825 MiB... There are some updates waiting to be installed.

[Maxim Veksler (maxim-vekslers)]

Top roller at 2.6%

[Cecil Reed (reedce1)]

Observed snap-store using over .5 GiB of ram

[Richard Chamberlin (rjdchaim)]

Also seeing this on a new (less than a week) install of 20.04. I run an older machine and this hogs my performance.

[GrzesiekC (grzesiekc)]

570 MiB here

[Carlos Pita (carlosjosepita)]

It doesn't seem intermittent to me. Isn't memory consumption always high (>300MB) for you?

[Carlos Pita (carlosjosepita)]

This probably has to be addressed upstream https://gitlab.gnome.org/GNOME/gnome-software/-/issues/942

[Tryfon Farmakakis (farmakakistryfon)]

Same here, 461MBs while running in the background on a relatively fresh, up-to-date Ubuntu 20.04.1 install. This is not OK.

[Rado Smogura (rsmog)]

I think:
1. Memory usage is too high when application is running.
2. Most important - the application stays in background after closing window and still consumes around 400MB of memory (this is a lot).

[Bambu Fan (bambufan)]

On my fresh Ubuntu 20.04LTS the snap store uses 1,1Gb of memory. I think that is insane and I will take action to disable or remove the program from my pc.

[Simon B. (bemymonkey)]

Still happening on a fully updated Ubuntu 20.04 LTS install.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[tuca (cos-rj)]

mee too 400mb

[Dave Jones (waveform)]

It appears to take 250MB resident (according to top) on my Raspberry Pi 400 even when the software is "closed". On a machine with 4GB, this is pretty significant. Even more so considering we now support the desktop on Pis with as little as 2GB of RAM.

snap-store eating my swap file

:(

[John Pye (jdpipe)]

I found that snap-store was consuming fully 1 GB of RAM on my system when I checked it just now. Such a huge memory use for something I *never* used. I would like to think that core elements of the a default Ubuntu system would be designed more carefully for low memory use.

[Kirill Shustov (kirill-sustov)]

I am running on fresh Ubuntu 22.10 installation.
snap-store consumes 500 MB of my system.

as a workaround I am closing this app manually. is there any better solution?

[Akshat Kumar (kumar-ubuntu-enthusiast)]

Hey Guys,
I am using Ubuntu 22.04.1 LTS x86_64. The problem still persists.

[Alex Lutay (taurus)]

On my Ubuntu 23.04 the snap-store uses ~26GB!!! of RAM in 7 days of uptime. o_0

Happy to help tracing it! How?
P.S. It could be the separate issue...

[Haui (haui111)]

Ubuntu 23.04, issue still persists.

[Dave Jones (waveform)]

This appears to be partially fixed under Ubuntu 23.10. While the application (when running) still eats a few hundred meg of RAM, it does release that when closed, as opposed to hanging around persistently. Given apt usually eats over a hundred meg when processing the archive index, it's probably reasonable for a a graphical application processing a similar archive and including all the icons and pretty graphics to gobble a few hundred meg. However, it should definitely relinquish that memory when not in operation, which now appears to be the case.

In other words, my major objection (that it grabbed this RAM even when not in use), appears to be addressed. However, that's not the subject line of the bug; should this be closed / revised? Are others still encountering issues with the store on mantic?

[Jeremy Bícha (jbicha)]

Dave, this issue still affects gnome-software which is still used by some Ubuntu desktop flavors as of 23.10. I intend to propose soon that
1) those flavors switch to the firmware-updater snap or the GNOME Firmware app for 24.04 LTS
2) allowing me to drop the firmware support
3) perhaps it would then be possible to stop GNOME Software from continually running in the background.

- Ubuntu's unattended-upgrades, update-manager, etc. handle updating .deb's.
- Snaps automatically update themselves.
- The default install did not have a way to automatically check for firmware updates though, which was considered a critical enough need that the Ubuntu Desktop team did not override the app always running in the background.

However, it looks like Flatpak does not have its own auto update mechanism currently. Hmmm…

On a second note, this issue is also marked as affecting snap-store-desktop which is the project for the older Snap Store still used in Ubuntu 22.04 LTS.

[Alex Lutay (taurus)]

@waveform (Dave Jones)

The issue is still reproducible for me on 23.10 (see the new attached picture).

Snap-store used 2GB RAM my laptop with 1 day uptime only
(and the RAM usage is growing over the time,
please check my screenshot in https://bugs.launchpad.net/snap-store-desktop/+bug/1879137/comments/36
26GB RAM used by snap-store there !!!)

Happy to help with tracing it, feel free to ping me in MM!
