Issue description

"http/tests/security/xssAuditor/svg-animate-clutter-2.html" is flaky.

This issue was created automatically by the chromium-try-flakes app. Please find the right owner to fix the respective test/step and assign this issue to them. If the step/test is infrastructure-related, please add Infra-Troopers label and change issue status to Untriaged. When done, please remove the issue from Sheriff Bug Queue by removing the Sheriff-Chromium label.

We have detected 3 recent flakes. List of all flakes can be found at https://chromium-try-flakes.appspot.com/all_flake_occurrences?key=ahVzfmNocm9taXVtLXRyeS1mbGFrZXNyRAsSBUZsYWtlIjlodHRwL3Rlc3RzL3NlY3VyaXR5L3hzc0F1ZGl0b3Ivc3ZnLWFuaW1hdGUtY2x1dHRlci0yLmh0bWwM.

Flaky tests should be disabled within 30 minutes unless culprit CL is found and reverted. Please see more details here: https://sites.google.com/a/chromium.org/dev/developers/tree-sheriffs/sheriffing-bug-queues#triaging-auto-filed-flakiness-bugs

This looks like an issue with the HTTP server setup for the http/tests LayoutTests (I see some tests got "Internal Server Error" in the test results looking through the link above.) Passing this to Blink>Infra, which seems more appropriate (but maybe not correct either...)

Flakiness dashboard looks pretty green: https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=webkit_layout_tests&tests=http/tests/security/xssAuditor/svg-animate-clutter-2.html

Taking this out of the sheriff queue.

Looks like a Swarming issue. Many input files suddenly disappeared during the test execution. Apache's error_log.txt (can be found in https://test-results.appspot.com/data/layout_results/win7_chromium_rel_ng/14273/layout-test-results.zip) is full of "file does not exist" (or similar errors).

Restarting the exact Swarming job succeeded.

Swarming starts deleting files once the main process stopped. If children processes are still running, they will show up in the stdout but may be surprised as the file system is disappearing underneath. This is (currently) WAI.

Other than that, you would probably have to retry locally and figure out what is happening exactly.

Per #6 could you change your tests to block on completion of all child processes?
