How to diagnose OOM dotnet applications in a container?

Question

.NET

There is a dotnet service in a container built on the basis
of mcr.microsoft.com/dotnet/aspnet:6.0

The service is launched in k8s and regularly crashes with OOM, and not just crashes, but explodes with 30% of memory usage immediately in OOM, no matter what limits you set for it

What Is there a way to create a dump in such a case?

Answer 1

1. Is it possible to run this service first without a container and see what happens on the local machine?

2. Usually such an explosion is preceded by some logs - run dotnet in diag mode: dotnet run --diagnostics. Containers, even dead ones leave some logs
