This is a timeout that would have previously been reported as bug 1339594. 21:43:06 INFO - Timeout waiting for test completion; killing browser... 21:43:06 INFO - Terminating psutil.Process(pid=31585, name='firefox')

Most of these are on Windows 8. A minidump is generated, but we get no crash report - as in bug 1310638.

https://hg.mozilla.org/mozilla-central/rev/f01503971a81 Matt, I can only find the one crash report - comment 5 - but I'm hoping this is the same issue that is causing frequent crashes on Windows 8 Talos, in this bug and others. Could you have a look?

That crash is very linux specific - and the same as bug 1341496. An equivalent crash on windows seem very unlikely to be something that would break the crashreporter (it'll hit a MOZ_CRASH and terminate, shouldn't corrupt the heap). It's possible that the crashreporter breakage is unrelated and is hiding the real crash for this, but that seems unlikley as we should see the MOZ_CRASH message still.

Recent linux crashes are as in bug 1341496. Recent osx crashes have no report. Recent windows crashes usually have no report, but here is an exception: https://treeherder.mozilla.org/logviewer.html#?repo=mozilla-inbound&job_id=87326559&lineNumber=7400

I assume fixing the win8 crashes and the linux crashes will make this almost go away.

mostly related to bug 1345735, would prefer to see that fixed before investing time in anything else.
