1. Run http tests, that force the http server to be spawed. In my case I used http/tests/webgl/1.0.2/resources/webgl_test_files/conformance/textures/tex-image-and-sub-image-2d-with-video-rgba5551.html in parallel 100 times. 2. Before it ends, press Ctrl+C to shut down the testing. 3. Goto 1. It will fail as the server could not be spawned.

In case WebKitBuild/GTK/Release/layout-test-results/error_log.txt mentions "Error: (17)File exists: unable to create scoreboard" the workaround is to manually remove stale SHM segments: https://makandracards.com/fabio-silva/49967-apache-unable-to-create-scoreboard-shared-memory-failure I suppose we could automate this though.

I think that clean up should be implemented before launching the server.

Tested locally and it's working as expected, cleaning the stale segments and allowing the server to start normally.

The proposed solution is to look for stale SHM segments, eg. segments TIL that Apache still uses SysV persistent SHM segments 🤯️
