Github Actions hanging with System.IO.IOException: No space left on device

🏷️ Discussion Type

Bug

💬 Feature/Topic Area

ARC (Actions Runner Controller)

Discussion Details

Starting 13.6. one of my apps (~20Mb node.js project, Azure App Service deployment) has had all build actions fail after 15min without changes in the workflow (or build/tsc). I guess it could be some broken code that passes/deploys locally but really smells like a Github-issue :| Also file listing includes files that are not present in my project like an issue in runner cleanup. I've done a ticket but no response.

Anyone seen anything like this?

This sounds like runner workspace cleanup or disk pressure more than an Azure App Service issue, especially if files show up that are not part of your repo. I would add one diagnostic step before the build to print df -h, du -h -d1 $RUNNER_WORKSPACE, and docker system df if Docker is used. If this is ARC, also check whether the runner pod has an ephemeral-storage limit or a reused work volume that is not being cleaned between jobs. As a quick workaround, clear the workspace and Docker cache at the start of the job, but I would still attach the disk output to the support ticket because "No space left on device" after 15 minutes usually needs runner-side evidence.
