Timeline
-
Investigating
Alert: error rate on Handler #6 crossed 3% for 5 consecutive minutes.
-
Identified
A stale session affinity rule after a config reload pinned a slice of traffic to draining workers.
-
Mitigating
Traffic shifted to Handlers #4–#7. Unhealthy workers were recycled.
-
Resolved
Error rate returned to baseline. The affinity rule was rolled back and locked behind a canary.
