Related to issue #516 . I experienced different types of symptoms: Sometimes an assertion failed (assertion that remaining locks == 0), sometimes the assertion passed but there was panic or slowness elsewhere, most times the test passed fine.
My knowledge of the projects techniques is still a bit limited, so I consulted AI, but I try to use my best judgement in evaluating whether its suggestions make sense. It suggested that the test may experience a race condition regarding to how quickly the locks are cleaned up in a 2PC, and that we could wait for the lock cleanup process to let the background process finish and then check the assertions.
