macOS Mojave Debug WK1 EWS queue is having 30+ layout tests failures intermittently. Sometimes during the same run, most test pass in retry. e.g.: https://ews-build.webkit.org/#/builders/32/builds/2 This started happening after OS upgrade on macOS EWS bots.
It looks like half of these are timeouts. And the failures mostly are actually harness timeouts as well.
Not sure if this is still happening. There was one suspicious case recently, where the patch doesn't look like is would have introduced 30+ failures: <https://ews-build.webkit.org/#/builders/32/builds/1228>. We should probably check back in a few more days.
Closing this since it doesn't appear to be happening anymore.
