Everything's crashing!

English Applications

I’m not sure if this is the right category, but I’m on Leap 15.4 with KDE, and starting yesterday, windows have been crashing erratically. Things would be running fine, but then I’d try to open another application window and I’d get a notification about KWin crashing; then more and more applications would follow, including the crash handlers themselves, until nothing’s usable. I’d restart the computer, and during some sessions no applications would last more than a second. I don’t know how to check what’s wrong, especially when I can’t even get System Settings for example to stay open.

Not sure if this is relevant, but yesterday when I ran my updates, it told me I had no space left in the root folder. I checked and the tmp folder had a load of files with Chromium in the name even though I very rarely use Chromium and wasn’t using it at the time. After I restarted my computer, the root folder usage had gone down on its own.

I managed to get one of the crash windows to stay open and copy this error log:

Application: The KDE Crash Handler (drkonqi), signal: Bus error

To me it looks very relevant. If your update failed because of to less space, then you probably have a broken system now.

Maybe a first action might be to repeat the

Thanks. That seemed to be the problem, that or my drive just being full. It seems to have sorted itself out; I guess after a few restarts some temporary files got autodeleted and it’s working much better. Trying to be safe now and reduce some of the clutter in /tmp.

There are several ways to get a clean /tmp. I fact I thought that the standard way openSUSE is installed is using a tmpfs for /tmp (which deletes the contents at every shutdown), But I am not sure about that (I have that construction on all my systems for a long time already).

That happens on Tumbleweed, but it is not the default for Leap install.

Thanks for the info.
