Don't really know whether this is a formerly-hidden shutdown crash now sort of hidden but managing to turn the run orange, or bustage from bug 812135/bug 808410, or something I'm not even noticing.

I believe this was an already-occurring issue that we'd previously been hiding, now brought to light by bug 808410 patch part 2, since we're not clobbering the return code after each run.

Geoff, I don't suppose you can see something in any of the logs that suggests why the return code from one of the individual test runs returned as non-zero?

I guess we could also print the return code after each iteration, to aid debugging this kind of thing.

It takes some searching, but yes, there are errors visible. In at least 2 of the logs I found:

ERROR: Unable to parse process list (bug 805969)

Ah thank you :-)

I wonder if Will would mind having those as "Automation Error", so TBPL's parser can see them...? Or else some other common prefix we can add to the TBPL regex list, that is less likely to get false positives than "ERROR:" (you laugh, but I'm sure we'll match against that during the desktop testsuites for a variety of things).
I confirmed that all of the logs reported here have the bug 805969 message. Here's a sample:

is being returned from sutAgent for another command (launching robocop?) and somehow getting mixed up with the response for the 'ps' command.
I was able to reproduce this once, locally, with extra logging. The corrupt response to 'ps' was received after some timeouts on a long-running testBrowserProvider.
Depends on: 814496
Incidentally, I checked and testBrowserProvider normally takes under 200 s, and most rc tests take less than 50 s, so there may be another bug behind this one which is causing tests to occasionally take much longer than usual to execute.
Haven't seen this or related problems since bug 814496 was resolved.
