I'm running Visual Studio 2010 SP1.

This is still not resolved (despite being marked as fixed).

5 tests run in parallel perfectly.

With 6 or more tests configured to run in parallel - all tests fail instantly saying "Aborted".

Why was this marked as fixed when it isn't?

I can reproduce on my 6 core processor (no hyperthreading involved).

I have a machine with 8 cores.

<Execution parallelTestCount="5">

5 tests run in parallel - everything works as expected.

<Execution parallelTestCount="5"> or
<Execution parallelTestCount="8"> or
<Execution parallelTestCount="0">

The test adapter 'UnitTestAdapter' threw an exception while running test 'X'. Thread was being aborted.

We are experiencing this same issue. It is marked as resolved; how so? Is this to be fixed with SP1, when it comes out?

The error I get is "Test run is aborting on '<machine-name>', number of hung tests exceeds maximum allowable '5'."
