Reported 2019-02-27 10:02:07 PST
TestWebKitAPI.ProcessSwap.NumberOfCachedProcesses seems flaky. In https://ews-build.webkit-uat.org/#/builders/19/builds/1299, the test Failed in run-api-tests step. However, in the immediately next retry step (re-run-api-tests), it passed.

Still noticed a flakiness in https://ews-build.webkit-uat.org/#/builders/19/builds/2249 This test failed in run-api-tests and re-run-api-tests steps, but passed in run-api-tests-without-patch step. Seems like a flaky test, unless that patch actually broke this test.

Another flakiness instance: In https://ews-build.webkit-uat.org/#/builders/19/builds/2256 the test Passed in run-api-tests step. However, in the immediately next retry step (re-run-api-tests), it Failed.
