page_cycler_v2.* timing out on chromium perf CQ

Project Member Reported by charliea@chromium.org, Nov 22 2016

Issue description

Revision range first seen: ??????

Link to failing run: https://build.chromium.org/p/tryserver.chromium.perf/builders/android_s5_perf_cq/builds/705

Link to example failing step log: https://build.chromium.org/p/tryserver.chromium.perf/builders/android_s5_perf_cq/builds/705/steps/page_cycler_v2.intl_ar_fa_he/logs/stdio

It seems as if all page_cycler_v2 benchmarks failed on that test run.

Excerpt from example failing step log:

Exception raised when cleaning story run:

ChromeClockSyncError: Cannot issue clock sync. No devtools clients

It appears as if Chrome is crashing. nednguyen@, should we remove this from the CQ if it's flaky?

If the test is disabled, please downgrade to Pri-2.

Disable is in the CQ (https://codereview.chromium.org/2520393002/).

kouhei@, do we still want this on the CQ?

Are we only having problems on android_s5_perf_cq? If so, we should just put the effort into turning that bot down instead of disabling tests. See  bug 665529 .
We're having some problems with other trybots as well, but that's the biggest offender. (Other errors I've seen are due to a known issue with system health benchmarks where the browser crashes.)
Status: WontFix (was: Assigned)
Going to go ahead and close this as WontFix: I'm only seeing this on the Android S5 perf CQ, and we're decommissioning that anyhow.
Sorry, realized my comment #4 was very misleading: this problem is only happening on this trybot, but some of the other trybots are experiencing other problems due to the system health smoke tests.
