No clue what was using it. Not the first time I've seen this.

So this bdw is indicates as having some other issues. But looking at the
visualization page I see that many other machines are failing to complete
the test run. It's a problem already in nightly, but it seems rather
strange to leave that out of this report. How can anyone be sure that
anything at all got tested if we just silently skip a significant portion
of the tests?

What's even more strange is that the bsw isn't listed anywhere. Looking
at the CI board it's only run 1 out of the last 5 runs. What's going on,
and why aren't these results telling us that something may be wrong on
that machine?
