[Flaky CI] Server starts timeout and no logs

[hnyls2002]

Checklist

The server boots always times out, and there is no logging (stderr) output in the panel. This behavior is not aligned with local running.

The unittest framework is configured with a timeout of 2000 seconds. If a single test case takes 2000 seconds to execute, it will report a timeout error. Could you first test locally to see if both test cases pass?
