TestWebKitAPI.WebKit.ServerTrust is failing consistently on ews158 since we upgraded OS on ews158 from 10.14.3 to 10.14.4. e.g.: https://ews-build.webkit.org/#/builders/9/builds/1270 https://ews-build.webkit.org/#/builders/9/builds/1278 https://ews-build.webkit.org/#/builders/9/builds/1288 https://ews-build.webkit.org/#/builders/9/builds/1296 https://ews-build.webkit.org/#/builders/9/builds/1302 This was added in http://trac.webkit.org/changeset/244568/webkit
This may be a configuration issue. I will take a look.

This doesn't appear to be happening anymore on this bot. I installed the iOS 12.2 SDK on the bots, so perhaps that resolved it.
