Description:
TestWebKitAPI.GPUProcess.WebProcessTerminationAfterTooManyGPUProcessCrashes
The first failure that I saw on the dashboard was on 9/22/2021 at r282903, but this does not appear relevant to causing this issue. This test has been flaky for its entire history on the dashboard.
History:
https://results.webkit.org/?platform=ios&limit=50000&suite=api-tests&test=TestWebKitAPI.GPUProcess.WebProcessTerminationAfterTooManyGPUProcessCrashes
Crash Log:
Child process terminated with signal 9: Killed
