chrome_sync_shell_test_apk failing many tests on linux_android_rel_ng

Project Member Reported by kbr@chromium.org, Jun 9 2016 
In this build:
https://build.chromium.org/p/tryserver.chromium.android/builders/linux_android_rel_ng/builds/84594

from this unrelated CL:
https://codereview.chromium.org/2052703002/

Many tests failed. I can't figure out where in the log the root cause is indicated.

There are a lot of purple builds on https://build.chromium.org/p/tryserver.chromium.android/builders/linux_android_rel_ng?numbuilds=200 . It looks like builds with test failures are showing up purple for some reason. This is probably inducing a lot of load on the CQ. Consequently I'm marking this P0. Please downgrade if my analysis is poor.

Yeah, it looks like we running over capacity yesterday afternoon, and most swarming tasks were forced to sit pending for a while and timeout, hence the purple. Lowering priority since we're back down to normal levels. I'm still investigating the root cause.

As for the build you linked, I think it might be that specific bot's fault. It's been failing around 50% of all its tasks, much higher than we're seeing from other, more reliable bots. These things have been the cause for a lot of flake recently. I'm investigating in https://bugs.chromium.org/p/chromium/issues/detail?id=617310

As John mentioned eariler, these two things could very well be related: unhealthy bots > tests flake > more retries > more tasks > we run over capacity > everything turns purple

Thanks Ben. Good investigation. Feel free to downgrade this to P2 or close as WontFix if the issues like bad devices are being investigated in other bugs.

I think we can close this.
