Overview
When using serial group, you might encounter situations where serial-start are failed instead of queued. This behavior is not a bug but an intended feature of CircleCI's pipeline priority system. It ensures that newer triggered workflow take precedence over older ones, maintaining version integrity and preventing deployment conflicts.
Solution
Why serial-start Are failed
The serial-start failure indicates that a newer pipeline has already acquired the lock for the same serial group. This is by design to ensure that only the most recent workflow are running, avoiding the deployment of outdated code.
Benefits of This Behavior
Efficiency: When multiple commits are merged quickly, the newest pipeline includes all changes from previous commits.
Integrity: Prevents older code from being deployed after newer versions, maintaining the integrity of your deployment.
Conflict Avoidance: Reduces the risk of deployment conflicts by ensuring only the latest code is deployed.
