I was able to reproduce the failure locally at TOT using run-webkit-tests --force --iterations 500 --exit-after-n-failures 1 webrtc/datachannel/mdns-ice-candidates.html -f

The test failed with r282200 with the same diff and passed with r282150.

It seems the test has been flaky for long time with different diffs.

Lately the test just has been fixed for a different diff in r283235 (Bug 230700).
