Description Ryan Haddad 2018-01-02 15:10:08 PST
The following layout test is a flaky timeout on macOS WK2

http/tests/resourceLoadStatistics/clear-in-memory-and-persistent-store.html

Probable cause:

This could be related to https://trac.webkit.org/changeset/226235/webkit

Skipped test in https://trac.webkit.org/changeset/226538/webkit because it is timing out very frequently on the bots.
Comment 3 Matt Lewis 2018-01-11 17:51:41 PST
It seems that after skipping this test another resourceLoadStatistics test began timing out as shown in this bug https://bugs.webkit.org/show_bug.cgi?id=181482
I'm wondering if they are related as both timeout with a failure to have notifyDone called.

Hopefully resolved in https://trac.webkit.org/changeset/227223, https://bugs.webkit.org/show_bug.cgi?id=181822.
