During an openQA test today, plymouthd crashed, causing plymouth-start.service to fail (the test was a check for failed services, so it failed). I don't know if this will be a consistent failure caused by a change introduced today, or if it's something periodic that might have been lurking already. The journal shows: Aug 01 04:02:02 fedora systemd[1]: Received SIGRTMIN+21 from PID 360 (plymouthd).

I'm seeing exactly the same issue on ~20% of our fleet. Always on the same machines, but happening randomly on these set of machines.
This bug appears to have been reported against 'rawhide' during the Fedora Linux 42 development cycle. Changing version to 42.
*** Bug 2336530 has been marked as a duplicate of this bug. ***
This message is a reminder that Fedora Linux 42 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 42 on 2026-05-13. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 'version' of '42'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, change the 'version' to a later Fedora Linux version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see it. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 42 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 Linux, you are encouraged to change the 'version' to a later version prior to this bug being closed.
Don't recall seeing this one lately. Letting it go EOL is probably fine.
Fedora Linux 42 entered end-of-life (EOL) status on 2026-05-27. Fedora Linux 42 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora Linux please feel free to reopen this bug against that version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see the version field. If you are unable to reopen this bug, please file a new report against an active release. Thank you for reporting this bug and we are sorry it could not be fixed.
