Original Ticket Description

All write operations to the production PostgreSQL cluster (pg-prod-cluster-01) are failing with connection timeout errors. Read replicas are still responding. Error: FATAL: connection limit exceeded (max_connections=500). Monitoring shows 100% connection pool utilization since 09:38 UTC.

AI Research BriefGenerated at Step 9

High-confidence match against Known Error DB: Connection pool exhaustion pattern. Root cause candidates: (1) Long-running idle transactions blocking connection release — check pg_stat_activity for idle transactions > 5min. (2) PgBouncer pool misconfiguration after last week's config push. (3) Application connection leak following deploy TKT-2024-0874. Recommended immediate action: EXECUTE `SELECT pg_terminate_backend(pid) FROM pg_stat_activity WHERE state = 'idle' AND query_start < now() - interval '5 minutes';` Escalate to DB Team (L2) if not resolved in 15 min.

AI Agent yielded control. Ticket placed in L1 engineer queue. Assigned to Priya Sharma. AI execution paused pending human resolution webhook.
