2nd time today had PAMAC crash my desktop

I've been having lots of apps running, listening to music, having Steam game in the background, Firefox etc.

And the moment I tried installing something in Pamac (easytag or GUI for another app), music stopped, the system froze for a brief time and the entire desktop was reset, like I just logged in.

When I started pamac again it said "waiting for another package manager to quit", like it didn't exactly logged off entirely.

This is the second time it happened today and always when I wanted to install something via Pamac in the middle of my system usage (lots of common apps running). I also had Steam running at the background both times. Same game.

As always, which log file should I check first?

Alright, this is what I found in journal, if anyone can "decipher it for me", who/what caused it? Thanks

This may happen either if pamac had crashed and left the lock, or because that time there was a DB check (set in pamac settings "How often to check for updates").

Seems like gnome-shell crashed.
Often happens with bad/incompatible Gnome extensions (3rd party mostly, but not only...). Disable all extensions and keep doing things to see if it repeats.

This is not fail-proof, as it uses system resources on its own.

Yeah it left the lock during update.

What are 3rd party extensions? I added only one that I installed myself from Extension plugin in Fireofx. All others came with Manjaro. Further, if I disable all I will lose Arc menu. :-/

Yeah, happened this evening, again. This time I started Pamac and deinstalled Dartkable. No problems. But when I wanted to update database, it crashed after 5-10sec.

As seen in the log:

And it faulted again with the same stuff:

дец 30 00:42:59 gnome-shell[1152]: toggling down object GInotifyFileMonitor that's already queued to toggle up
дец 30 00:43:02 systemd-coredump[15059]: Process 1152 (gnome-shell) of user 1000 dumped core.

Alright, this was before the latest system update... will check out later. So many new versions.

Wanted to test it and it happened again under same circumstances. Luckily, maybe because of the latest system update of Manjaro, none of my apps crashed. Everything continued going. Though gnome-shell issued crash report when I looked at journal:

You mean Steam running in background?

The last log includes mozilla, not pamac.

Do you mean you used pamac??

In Gnome Tweaks (extensions.gnome.org)?

  1. Yes, Steam and my game running in the background.
  2. Yes, I've seen Mozilla in logs but this happens when running pamac!
  3. Yes I used pamac and deliberately wanted to update DB files to test the system. Because that's when gnome-shell crash happens.
  4. Alright, I wanted to be sure, but I disabled all gnome extensions that I turned on or installed. I left those that came with official Manjaro.

And as I said, luckily there are no other crashes anymore (since latest manjaro update). All other apps remain working. Even gnome-shell just restarts itself. If it weren't for sudden Pamac window switch to other app, I wouldn't even know that gnome-shell crashed! But alas it left a fingerprint in the journal.

I understand, but it could be a coincidence...
You might want to follow this (check for gnome crashes), or use pacman for some update/install activities to see if there is some similarity/difference.

Good idea, next time I will start pacman instead of pamac.

Well, my system is rock solid if it weren't for this. I can stress it out so much with image and raw apps and all kind of content and high memory usage... No problems.

I'm still experimenting but I think it had to do with no-swap partition. I didn't have any nor Manjaro asked me when I installed it.

However, certain image apps like GIMP and RawTherapee use a lot of memory when saving/finalizing image (not all the time, but more like "bursts" of data). It could be that at one point system ran out of memory and just crashed certain apps (including gnome shell).

I'm now using 16gb swap partition, together with 32gb ram. In my heavy-stress usage in GIMP (created 60x30k pixel image with fractals), saving and multitasking uses up to 11gb of swap AND 100% ram. Without it, saving those big files and stability just wouldn't be possible.

Swap is a little cost to a true safety catch, especially on a machine that is intended to do heavy image editing and retouching.

Happy New 2020 year everyone! :smiley:

That being said, crashes still happen when gnome-shell reaches +500mb in size. I disabled all extensions and it reached about 600mb until it happened again. First pamac dumped cores like 4-5x, even though I didn't see anything, but it logged.

Then after a while, gnome-shell dumped core and two windows had unresponsive close/minimize controls. But otherwise the system kept working. Although I lost keyboard control. Mouse was functioning normally, I could do everything with it, but keyboard was dead.

Still, until I fix this issue or find a workaround, I'm sad that I won't be able to use it for my job... Because gnome-shell (when it's over 500mb size) tends to crash during GIMP image saving too.
