I suspect this indicates a bad timing dependency in tearing down the server. I have seen this a couple of times with parallel tests and never otherwise.

For me, this consistently happens when I run parallel tests, and never otherwise.

But on pqm, which is not running parallel tests (afaik), it does occur:
