memory.long_running_idle_gmail_tbmv2.reference occasionally flaky on Mac Retina Perf (2) |
||||||||||||||||||||
Issue descriptionBot: https://build.chromium.org/p/chromium.perf/builders/Mac%20Retina%20Perf%20%282%29?numbuilds=200 Most recent failure: https://build.chromium.org/p/chromium.perf/builders/Mac%20Retina%20Perf%20%282%29/builds/3414/steps/memory.long_running_idle_gmail_tbmv2.reference/logs/stdio Screenshot: https://console.developers.google.com/m/cloudstorage/b/chrome-telemetry-output/o/profiler-file-id_0-2016-06-22_01-02-3230533.png The screenshot shows that this is due to a renderer crash. This happens very rarely (3× in the past 200 builds).

Any thoughts?

Even if we found the culrpit, I think our action item would just be "update the ref build", which is not different from if we don't find the culprit. I think let just disable the benchmark on ref build Mac with the ShoulDisable() decorator

The flake is very rare (4 times in the last 200 builds: https://build.chromium.org/p/chromium.perf/builders/Mac%20Retina%20Perf%20%282%29?numbuilds=200), so there's no need to disable (sheriffing guide says benchmarks should be disabled if they're failing "more than one out of five runs"). Let's hope updating the ref build will fix this.
