I don't see more than this one failure on https://ci.chromium.org/buildbot/tryserver.chromium.linux/linux_chromium_asan_rel_ng/?limit=200 right now, so marking only P2.

 
kbr@ is this a new failure?

All I know is that the test flaked on the CQ. I haven't looked at the flakiness dashboard https://test-results.appspot.com/dashboards/flakiness_dashboard.html for example to see if it's happening more often.

The chromium-try-flakes tool shows that it's slightly flaky:

miu@: I couldn't pull up logs for some reason.  Can you take a look at the failure mentioned by kbr@?
