Comment 2 Robert Jenner 2022-03-14 18:30:06 PDT 
I was able to reproduce the failure at iOS15 Release ToT using the following test:

run-api-tests --ios-simulator TestWebKitAPI.GPUProcess.ExitsUnderMemoryPressureWebRTCCase --release --verbose

I have not been able to discover the regression point because my simulator does not want to run on the debug builds I am downloading.
Comment 3 Ryan Haddad 2022-03-31 10:27:55 PDT 
Can we disable this test for now? It is slowing down EWS.
Comment 4 youenn fablet 2022-04-07 05:35:19 PDT 
This seems iOS specific, so we should probably reenable it in MacOS.
And maybe split the test to better understand the issue.
