Hi,
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.
At Azure I can see that within a few minutes (1-2 minutes) the socket connections jump from a few to multiple tousend:
At IIS we see the same/similar situation - the TCP connections are not increasing (blue/gren line), only the request count jump from 700/min to 1200/min
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

Hi @ThomasKehraus
I have two questions;
- Do you use Redis in your app ?
- Could you share your Abp Nuget package version ? Upgrading it to latest 6.x might help to improve the performance.
Thanks,
