DrKonqi Crash Log

[amshafer]

Sorry for the late follow up, but can you please provide any details for how you triggered this crash? was this on startup or while performing some action?

[mrdev023]

I couldn't reproduce the bug precisely. When, i working on my computer, after few hours, i see plasma crash and then plasma restart automatically with drkonqi window. I see also plasma crash when i not used my computer but just keep my computer running. It crash between 2-3 times by day.

KWin continue to working during plasma crash.

I have the same issue for some time now, the cause is also egl-wayland egl-wayland 4:1.1.16-1

[1nikolas]

Have this issue in wayland since the explicit sync update. Still happens in 565.. Can provide the full log if necessary

[amshafer]

We still haven't been able to reproduce this internally. Since the crash is happening in egl-wayland it would be very helpful if someone could build egl-wayland from source and get a crash with debug symbols. I'd like to confirm if this is the same problem as #145 tries to fix.

I can do this later, or try to use KDE Plasma crash handler function to download debug symbols.

[1nikolas]

I already tried to download the debug symbols many times, it seems broken always gets stuck for me..

and yes, the crash is caused by send_explicit_sync_points , and is the same problem as #145

[tobiasozor]

For me, the crash happens after a certain threshold of received notifications or clicks on the systray/widgets (e.g. clipboard, audio applets/plasma-notes) is reached. If I run this:

for i in {0..300}; do notify-send -t 500 $i; done 

then plasmashell will always crash after ~220 iterations (edit: ~220 iterations since the last crash).

pid="$(pgrep plasmashell)"; for i in {0..300}; do [ "$pid" == "$(pgrep plasmashell)" ] && notify-send -t 500 $i; done

For me, the crash happens after a certain threshold of received notifications or clicks on the systray/widgets (e.g. clipboard, audio applets/plasma-notes) is reached. If I run this:

for i in {0..300}; do notify-send -t 500 $i; done

then plasmashell will always crash after ~220 interations.

I'll try running this on my PC. Edit: tried, and yes, it also crashes Plasma on my PC, but far quicker for me, first time after 200 iterations, 2nd after ~160, and now after 68, so I think this also might be a bug in Plasma, not in just egl-wayland.
