Have you investigated the failure? Does it repro for you?
The symptom looks the same as #66424. If it is actually the same then I don't think it is a test problem, so we should not disable the test.

I didn't get time to investigate and might not get at least until next week. Since this test was "outerloop-blocking" I had to disable it until then.

Sounds good, just keep #66424 in mind when you get a chance to investigate it, the dumps there seemed to be corrupted so we are waiting to gather more information.
