/run/user/$id full and breaks other apps

[nicolas-delqueferre]

Hi,

Yesterday I encountered this error :

I tried running another flatpak (Visual Studio Code) but it wouldn't run ... I saw that my tmpfs was full, with chromium taking pretty much all the available space (1.6G)

df -h | grep user
tmpfs           1.6G  1.6G     0 100% /run/user/$id

du -sh /run/user/$id/*/*
0	/run/user/$id/app/com.mattermost.Desktop
1.6G	/run/user/$id/app/org.chromium.Chromium
24K	/run/user/$id/app/org.mozilla.Thunderbird

I don't know the root cause of this problem, but today, I've downloaded a file and save the content on my download's folder (/home/user/Downloads) (around 10G) and it happened again

du -sh /run/user/$id/app/org.chromium.Chromium/.*
0	/run/user/$id/app/org.chromium.Chromium/.flextop-lock
0	/run/user/$id/app/org.chromium.Chromium/.org.chromium.Chromium.6zWKZ3
1.6G	/run/user/$id/app/org.chromium.Chromium/.org.chromium.Chromium.d07p4H
0	/run/user/$id/app/org.chromium.Chromium/.org.chromium.Chromium.vg13r8

The problem is that every other app (for example, Thunderbird Flatpak) that try to write to this space cannot ( I can't send a mail because this space is full)

The only workaround I found is to log out and log back in to clear the space.

Thanks for your help !

Huh seems like Chromium is downloading everything to $TMPDIR first? That is...strange. Did you customize your downloads folder or ever modify Chromium's permissions?
