Description

A bug in the createdump tool which causes double crash dumps to be created for a single crash when running in a Linux container in Kubernetes.

Reproduction Steps

https://github.com/kristjanjogi-msft/createdump-doubledump-bug

Prerequites

  1. .NET 7 SDK
  2. Docker Desktop with Linux containers and Kubernetes support

Steps:

  1. Clone the repository:
    git clone https://github.com/kristjanjogi-msft/createdump-doubledump-bug.git

  2. cd createdump-doubledump-bug

  3. Build and publish the crashing application:
    dotnet publish -c Release -o published CrashingApplication/CrashingApplication.csproj

  4. Build the Docker image:
    docker build -t crashingapplication:1.0 .

  5. Run a Kubernetes pod in which the createdump tool creates two crash dumps for a single crash:
    kubectl apply -f doubledump.yaml

  6. View the evidence, two crash dumps instead of one are created:
    kubectl logs doubledump

Expected behavior

One crash dump is created for a single crash.

Actual behavior

Two crash dumps are created for a single crash.
