The timeout is showing up on EWS as a flaky test.
Comment 3 ayumi_kojima 2021-08-30 15:23:28 PDT
Seems like the test is flaky crashing on Big Sur E Release but I am not sure if this is a real crash because many api tests are crashing in the same test run with no crash log in stdio https://build.webkit.org/#/builders/105/builds/2914/steps/17/logs/stdio. 

I was not able to reproduce the timeout locally using run-api-tests --iterations 50 --ios-simulator TestWebKitAPI.WebKit.TryUsingPrewarmedProcessThatJustCrashed.

Test is now a constant timeout on iOS15. 

Reproduced test results locally on ToT (r283615) with run-api-tests --ios-simulator --iterations 50 TestWebKitAPI.WebKit.TryUsingPrewarmedProcessThatJustCrashed.

Poke for reviewers, it would be good to get this test passing on iOS bots.
