Components: Infra
Labels: Infra-Troopers OS-Mac
Summary: browser_tests on Mac10.11: Crashing in Crashpad. (was: browser_tests failing on chromium.mac/Mac10.11 Tests)
Skimming the code, it looks like Crashpad is having a hard time checking in with the bootstrap server, and is failing the subsequent CHECK.

Most recently, all the failures seemed to happen in one swarming task running on vm147-m1: https://chromium-swarm.appspot.com/task?id=3eaa0fdad5019810&refresh=10&show_raw=1

Adding `Infra-Troopers`, as this could possible be a bot issue?

Comment 2 by mkwst@chromium.org, Jul 13 

The next run also failed only on one swarming task, but running on a different bot: vm143-m1 (https://chromium-swarm.appspot.com/task?id=3eab223a38a88010&refresh=10&show_raw=1).

this is a persistent issue -- something in browser_tests is flakily killing the window server, dropping the bot into an unusable state for subsequent tests.
