MSTest Results "In Progress" - mstest

Question

Once in a while we are getting strange results from MSTEST. All Unit Tests seem to started at the same time - MSTest is just triggering them and moving on. After all of them are started the test run is aborted.
What seems strange is the Result "In Progress" - I can not find anything about such result in MSTest documentation.
MSTest is started and executed from within Jenkins and most of the time everything works fine as it should.
Any help or ideas about the situation would be appretiated.
Here is the exact output with test names deleted:

Try make QTAgent32 large address aware.
Had the same issue with a build server running Jenkins and MSTest, a bunch of tests reported status "In Progress" and was later aborted.
This helped:
Start a Visual Studio Command Prompt (Run as administrator might be needed)
Execute the following:
C:>editbin "Program Files (x86)\Microsoft Visual Studio
11.0\Common7\IDE\QTAgent32.exe" /LargeAddressAware
