Can you please check if this still occurs with systemd-246.12-1.fc33 (currently in updates-testing)?
(In reply to Zbigniew Jędrzejewski-Szmek from comment #1) > Can you please check if this still occurs with systemd-246.12-1.fc33 > (currently in updates-testing)? I see systemd-246.13-1.fc33.x86_64 and have installed it. So far no coredumps after an hour
OK, let's assume it is fixed.
FEDORA-2021-1c1a870ceb has been submitted as an update to Fedora 33. https://bodhi.fedoraproject.org/updates/FEDORA-2021-1c1a870ceb
FEDORA-2021-1c1a870ceb has been pushed to the Fedora 33 stable repository. If problem still persists, please make note of it in this bug report.
