[webkit-dev] Mac and Chromium Mac EWS

[Eric Seidel]

It's also possible that the NRWT "don't peg the machine" heuristics
are failing for the EWS bots.  You'd have to SSH in to know.  But if
you see it running too many DRT processes (or too many associated
Python processes) we can change the heuristic:
http://trac.webkit.org/browser/trunk/Tools/Scripts/webkitpy/layout_tests/port/base.py#L166

Also, if tests are crashing, we don't account for the CrashReporter in
our heuristic, and it has a bad habit of pegging one or more cores. :)

I connected up to one locally and the cpu was pegged and the machine was unresponsive.  I couldn't even open a terminal session.  I've had to reboot them with a power cycle.
