This is caused by https://github.com/dotnet/corefx/issues/3793 (I added a cause for it last week and its listed on the front page). Given we're hitting this a lot and we're not going to see a fix from .NET for a while, we should probably consider submitting a PR to xunit to make them avoid this path.
