We are facing the problem, that suddenly the backend (asp.net core) is not proccessing requests anymore. We have tried it with Azure AppService and also with IIS - both show the same situation. The application is running fine during the night and in the morning hours, few people are logging in and then we can see that the requests get queued in IIS and will not be proccessed - multiple AppPool recycle will solve the issue - some times.
In both environments the application stop proccessing further requests.
Did you see such a situation and can you help us to identify what could be the root cause? We are using: ASP.NET CORE & Angular .NET 5.0 v10.2.0
Thank you Kind regards, Thomas
