This problem is probabilistic. I run Python3 all test cases on OBS. In recent months, there have been about three times that the test cases hang on probabilistically. The current version with problems is 3.10.2, this problem has also appeared in 3.10.0 and 3.9.9.

I previously suspected the patch d0d83a9 (d0d83a9) fixed this problem, so I upgraded python3 to 3.10.2, but the problem still occurred.

The problem occurred again on these two days. There are a lot of errors after forcibly interrupting the task.Please refer to the attachment for details. It has appeared on the arm architecture machine several times recently.
