First spotted 08-29-2024. 08-28-2024 does not have logs for a different issue. 08-27-2024 did not hit the problem.

Packages diff:
lorax-packages.log.diff.txt

Last week occurence: 30 / 7 dailies which is 1/50 test runs.

This is weird, it looks like the Anaconda is turning off the logging log gets released and somehow it changes into SIGTERM signal processing...

[jkonecny12]

I just saw this in the python documentation:

If you are implementing asynchronous signal handlers using the [signal](https://docs.python.org/3/library/signal.html#module-signal) module, you may not be able to use logging from within such handlers. This is because lock implementations in the [threading](https://docs.python.org/3/library/threading.html#module-threading) module are not always re-entrant, and so cannot be invoked from such signal handlers.

https://docs.python.org/3/library/logging.html#thread-safety

I wonder if this is not the issue we are hitting.

Since 10-11-2024 appearing also on daily-iso

I think it is caused by porting Wayland patches (rhinstaller/anaconda#5829), adding image packages diff:
lorax-packages.log.diff.txt
Also: rhinstaller/anaconda#5829 (comment)
