Cakephp 3.10 - SplFileInfo::openFile dies while /tmp/cache/routes updates. File created with extreme protections

Need Help
1

Once this error appears, NO page will load. This error is all we get until I turn off Windows 7 file protections using the registry. Delete the file E:\someapp\tmp\cache\routes/\myapp_cake_routes_route_collection and then turn on Windows 7 file protections again!

ERROR log follows:

Seems weird that it’s got “/” in the path. Dunno if that’s part of the problem, but indicative of something not quite configured right?

Check permissions / ownership of the file when it’s running okay, and when it starts to fail. Maybe somebody is running a command-line task under a different user, which is giving the file permissions that the web server user can’t access?
