# Pipelines being triggered with Stale Artifacts

### Issue <a href="#issue" id="issue"></a>

After a Spinnaker upgrade, one or more pipelines is triggered with old/stale artifacts. This can be caught by the build number moving back on the affected pipelines from a bigger to a smaller value (eg. from build # 100 to 20). This behaviour has been observed on pipelines with an ECR and Jenkins trigger.

### Cause <a href="#cause" id="cause"></a>

While the cause has not yet been confirmed, the culprit is suspected to lie with leftover stale data in Orca's queue, left in there prior to the upgrade.
