We collected a core dump of our productive ASP.NET Core application using dotnet-dump collect -p <PID>.
Loading it into Visual Studio and running diagnostic analysis revealed some interesting stuff. However, two of the analysis results I’m not sure how to investigate further:
AA0013 Multiple exceptions were found on the heap
Clicking on one of the message shows some exception details:
The exception details do not contain stack traces, so I have no idea, where these exceptions are coming from.
Question: how can I troubleshoot this further? Why don’t I see any stack traces? Do I need to collect the core dump in a different way in order to get more details?
AA0003 Finalizer Queue may be blocked and cause high memory usage
Here I don’t see any useful details.
Question: how can I troubleshoot the root cause of this further?
