We're seeing many tests "crashing" without crashlogs on Ventura, with only the following in stderr No crash log found for com.apple.WebKit.GPU.Development:82267. stdout: stderr: com.apple.WebKit.GPU.Development terminated (pid 82267) for reason: crash https://build.webkit.org/results/Apple-Ventura-Release-WK2-Tests/256705@main%20(193)/results.html

@Miguel: I looked at the logs and the issue is that the GPUProcess is getting suspended by RunningBoard while holding locked files. Note that as far as I know, we don't expect process suspension on macOS at the moment so this is an issue. Also note that this is with an open source SDK, where you recently disabled our RunningBoard code at runtime. However, I suspect this issue is with: Source/WebKit/Scripts/update-info-plist-for-runningboard.sh Which updates our plist to opt into running board management and this logic likely still applies to the open source SDK builds, even though you completely disabled our RunningBoard logic there.

Created attachment 463546 [details] test list I can reproduce this on a (customer) Ventura install with the attached test list ./Tools/Scripts/run-webkit-tests --test-list <path-to-download>/repro-crash --no-retry
