+
+Investigating why the command `npm` hangs in the [offical NodeJS images](https://hub.docker.com/_/node) when run in GitHub Actions.
+
+Daily builds of my [FoundryVTT Docker repo](https://github.com/felddy/foundryvtt-docker) started failing between daily builds:
+- `2023-09-18`: ✅ https://github.com/felddy/foundryvtt-docker/actions/runs/6221059494
+- `2023-09-19`: ❌ https://github.com/felddy/foundryvtt-docker/actions/runs/6234099414
+
+The build of the `linux/s390x` image started hanging when running `npm install`.  
+
+This repository runs a simple [GitHub Action workflow](https://github.com/felddy/npm-hang-test/actions/workflows/build.yml) that runs `npm -v` during a Docker image build for several architectures and Linux distributions.
+
+Possible culprits:
+- https://github.com/actions/runner/actions
+- https://github.com/nodejs/docker-node
+- https://github.com/qemu/qemu
+- https://github.com/docker/buildx
