--- Comment #15 from Yifan Jiang
(In reply to robert Horn from comment #10)
The problem looks like it begins with Windowmaker. It starts at 10:15:53. The first visible symptom was at 10:16:02 when firefox startup failed. It brought up the profile manager selection list, then with a couple seconds that window vanished.
The log shows that Window Maker crashed (segfault). Then GDM terminates the X server and then all applications go down with IO error.
This is expected behavior and it is also what I was able to simulate on my test machine by killing wmaker manually.
I do not understand how you were able to see a new window for couple of seconds after that. Perhaps the high CPU utilization caused delay between the wmaker crash and the X server termination. However in comment 3 you said that only individual applications are killed, not the whole X server. I don't know how to explain that.
Nevertheless, whatever is happening, it seems to be triggered by crash in Window Manager. We should try to fix that. Can you check if you have any wmaker coredump recorded in the output of `coredumpctl`? If yes, please export it using `coredumpctl dump <pid>` command and attach it to bugzilla.
Hi Michal, A couple of seconds before wmaker crashed, it looks firefox complains something I couldn't understand. Can that be linked to you analysis as well? Thank you!
