It's normal behaviour of the kernel to try to swap and then kill processes if ran out of memory. Please tell us more about your system.
(In reply to Raphael Groner from comment #13) > It's normal behaviour of the kernel to try to swap and then kill processes > if ran out of memory. > Please tell us more about your system. I have 15.7 GiB of memory and 24.1 GiB of swap space. I see no oom message on this date via journalctl. I know the swap space was less than a quarter way full when this happened.

Happened again for me. I believe my crashes were triggered by a crash of dnfdragora-updater. See also bug 1684753 for another crash of xfce4-panele, likely caused by dnfdragora-updater Possible related dnfdragora-updater bugs: bug 1667903 bug 1669816 bug 1707500
This message is a reminder that Fedora 29 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 29 on 2019-11-26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '29'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 29 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 29 changed to end-of-life (EOL) status on 2019-11-26. Fedora 29 is no longer maintained, which means that it will not receive any further security or bug fix updates.
