On 1/11 this test flaked 18 times on mac_chromium_rel_ng. This is one of the top sources of flake in the chromium code base.

Mohamed, could you fix that or disable it overall? The tsan failures are due to Issue 917380 (should be fixed later today) but the rest is due to the test itself...

Mohamed, I decreased prio to P2 (for fixing the cause of the flakiness). If no more work is actually needed, please close the bug. |
