[2021-05-21T21:42:28.276Z] Cannot create directory for shared memory usage: /dev/shm/AzureFunctions
[2021-05-21T21:42:28.276Z] System.IO.FileSystem: Access to the path '/dev/shm/AzureFunctions' is denied. Operation not permitted.
```

No source file, test, or entry point is identified in the report. Reproduce the startup behavior on macOS with versions 3.0.3442 and 3.0.3477, then investigate the reported /dev/shm/AzureFunctions permission warning; done means the tool starts without this warning or its cause and expected behavior are documented.
