I have several websites made by asp.net core 6 running on IIS 10.
These days my websites sometimes strangely stop in application pools.
The application pools stop with this information in event viewer:
The description for Event ID 0 from source gupdate cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
Service stopped
I have asked similar problem before. Someone tell me to try to catch the asp.net core exception first.
After I add an exception middleware to my asp.net core project. In spite, it catches some exceptions with any other bugs. However, when the application pools crash and stop, it catches nothing.
What's wrong with it and how can I solve this problem? Thank you.

Your other post has an Exception code: 0xc00000fd which indicates a stack overflow error. Most likely this is a bug in your code.

2021-12-27T02:29:58.297+00:00 Yes, there is another error related asp.net core in Event Viewer. However, the error does not mention something like service stop so I consider it may not cause this.
It is so troublesome that the application pool stops without any regulation.
Maybe one day stop one time, or three days stop one time. I can hardly debug it.

2021-12-27T03:23:15.857+00:00 I have an idea that uses the visual studio to attach the process to the remote server. When the exception occurs again, the visual studio will report the error at once. Can I try this? Or is there any better way to solve this?

2022-01-01T14:14:25.213+00:00 Hi, the site you provided is about support for Microsoft 365/Office/Outlook/OneDrive/Windows/Surface devices/Xbox/Microsoft Teams/Microsoft Store/Microsoft Edge while not for IIS yet.

2022-01-01T14:24:55.77+00:00 Most likely this is a bug in your code not IIS. Add logging to your code so you can figure out what where the bug is located. You can also share your code on GitHub and ask the community to review your code.

2022-01-01T14:28:00.86+00:00 It is so strange it never throws any exception even I added try&catch middleware to my project. I consider maybe it is not the problem of the project.

2022-01-01T15:15:37.913+00:00 Again, I recommend adding logging which is a fundamental feature in ASP.NET Core.
Logging in .NET Core and ASP.NET Core
Keep in mind, you have not provided any useful information about your application. How does the application work? What problem does your application solve? Can you explain what crashing means? How do you detect a crash? Does the site report "service unavailable" until the application is restarted?
Keep in mind, IIS has been around a long time. It's doubtful the problem is IIS.

2022-01-02T00:09:33.847+00:00 I have added logging while not logging anything while crashing.
The site will report "HTTP Error 503. The service is unavailable." while it crashes.
As you said, if I upload my code to GitHub and find out the problem by someone is the best choice. However, it is an important project of our company that I can't upload to anywhere.
In spite of it being stupid and troublesome, but it seems I can only find some ways to debug or catch the error.

Logging only works while the application is running which is covered in the docs. If designed correctly the logs contain entries from the time the application started to the point the application crashed.
Try Application insights since you cannot share much information on this forum.
