We have an IIS 7.5 website running on Windows Server 2008 R2, and one of the virtual directories is on a separate server, accessed via a UNC path.
Every now and then (several times a day) the ASP.Net application restarts, and in the event log we get:
"Event message: Application is shutting down. Reason: Configuration changed."
The App Pool is running in Integrated Mode and has "Disable Recycling for Configuration Changes" set to True.
We know that the configuration has not changed (we don't even have any config files in this directory), however we are able to recreate the problem in a test environment by temporarily making the UNC path unavailable, and then requesting a file from it.
Any suggestions on how to resolve this issue?
Steve.
