systemd-journald[701]: Journal stopped

Solely a SysRq + R, E remediated it. However, then, I lost the ability to log in at any of the available ttys, so I was forced to I, S, U, B.

Those are not duplicate lines. If you look to the right end you will see each is related to a different process number, thus it is opening multiple processes

Where did you install Warp Terminal from? It does not appear to be a fedora package.

If it was installed from www.warp.dev or github then it is a 3rd party application and it is not likely that anyone here would be able to answer the question. Probably best if you approach the developers about this.

@computersavvy, I’ve asked here because all that I see are PowerShell logs (installed via dotnet tool install --global PowerShell), which is provided by dotnet-host-10.0.0~rc.1.25451.107-0.8.fc43.x86_64 (per rpm -qf $(command -v dotnet)), [1] and if I ask Warp, they’ll say they’re unfamiliar with KWin and PowerShell, whereas if I ask PowerShell, they’ll say they’re unfamiliar with Warp, KWin, and Fedora.

Additionally, this was a hang of the compositor, so something went wrong at a very low level that shouldn’t have. Regardless of the package that hung it, it shouldn’t have hung. I’d have asked this at KDE’s Discourse instance, but many of them definitely aren’t familiar with Fedora, Warp, or PowerShell. This is where the most relevant disciplines intersect.

However, you’re correct that I should file a bug upstream, at least. I’d like to start with Warp, and see whether they direct me to PowerShell, etcetera. However, Warp doesn’t want bug reports for their pre-release packages unless well-diagnosed, and this hasn’t yet been reproducible. Consequently, I require some assistance in pinpointing exactly what package caused it.

Do you state that because I should have retained some? If so:

Perhaps, it was due to:

Shame that I wasn’t able to report the ANR via drkonqi or abrt:
