A fortnight ago, I updated our QB production system from version 13.0.15 to 15.0.26 and the JDK from 11 to 21.
Now I have noticed that the artifacts are no longer being deleted regularly.

Our global settings in the root:

Build Cleanup Strategy | Reserve builds by days (10 days)
Artifact Cleanup Strategy | Reserve artifacts for specified number of builds (4 builds)
Our system maintenance schedule time is once a day at 23:50.

But the only thing that is displayed in the server log is (There are several lines, I have only inserted the last one here: Removing ...)

But no information about the deletion of the build artifacts



Now I have installed a minimal QB 13 version that only has one configuration, 'Test', which publishes a file every 100 seconds
And when the System Maintenance Task ran, the build and artifacts were deleted as expected.
Here are the log outputs from QB version 13

Then I updated this QB13 version with QB version 15.0.26. After that, some builds ran again and when the system maintenance task ran,
ONLY the builds were deleted, not the artifacts (as is also the case in our production system).
And here are the log outputs from QB version 15

We're in a bit of a rush because the disc is filling up and we have to delete files manually now.
