User-936241996 posted
I recently upgraded to Windows 2019 Server for my development environment. After reinstalling my ISAPI extensions, I am encountering an access violation when the extension terminates. This seems to be happening
AFTER TerminateExtension() completes. I have both added code to create an event in the event viewer, and removed all code executed in the exported TerminateExtension() function. It doesn't make a difference. Also, I have checked the permissions
in the internet cache folder, and turned off compression for static items. The error still occurs.
The name of the extension is 'iisapi_caddata.dll.' As you see below, the Fault Module Name is 'iisapi_caddata.dll_unloaded.' This seems to cause no problems, unlike programming errors I have made
where iisreset must be run before the web server is able to be relaunched.
The event created is strangely similar to a post at Rick Strahl's web log: ISAPI-Module-Crashing-on-Application-Pool-Shutdown
Does anyone have any thoughts?
