I noticed this and continued. If I debug my Azure WebRole locally, in Visual Studio 2013, and I pause at the breakpoint for too long, the current request, or the next, and all subsequent requests will result in error 500.19 - Internal server error.
HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.

Event Viewer says:
The worker process for application pool '902aa9af-0ed8-4126-be43-e533339bdeef' encountered an error 'Cannot read configuration file' trying to read global
module configuration data from file '\\?\C:\Users\<user>\AppData\Local\dftmp\Resources\11468ba0-d99a-45d2-bcce-eae28c7b4e2f\temp\temp\RoleTemp\applicationHost.config',
line number '0'. Worker process startup aborted.
And if I go check this directory, I see that this file is not there. I assume the file was there at some point, because I could make requests before that.
Restarting WebRole seems to fix the problem.
