Root Cause

A GitHub Actions workflow run is cancelled because a newer commit to the same branch triggers another run in the same concurrency group. The cancel-in-progress setting supersedes the older run.

generic

Workarounds

  1. 90% success Use branch-aware concurrency groups with cancel-in-progress only for non-default branches 
    Set 'concurrency: group: ${{ github.workflow }}-${{ github.ref }}' with 'cancel-in-progress: ${{ github.ref != 'refs/heads/main' }}' to only cancel in-progress runs on feature branches
  2. 82% success Disable cancel-in-progress and let jobs queue instead 
    Set 'cancel-in-progress: false' in the concurrency block so that newer runs wait for the current run to complete instead of cancelling it

Dead Ends

Common approaches that don't work:

  1. Remove the concurrency configuration entirely 60% fail

    Without concurrency controls, multiple runs pile up consuming runner resources and potentially deploying out of order

  2. Set a unique concurrency group per run using run_id 85% fail

    Using a unique key per run effectively disables concurrency control, defeating its purpose entirely
