Background scheduler services exceed loop intervals under database contention

Prefect background services (RecentDeploymentsScheduler, FlowRunNotifications, FailExpiredPauses) take longer to complete than their configured loop intervals, indicating database or resource contention. RecentDeploymentsScheduler can take 160+ seconds against a 5-second interval.

These warnings are symptoms of underlying database performance issues. Address database query performance, connection pool sizing, and lock contention. Monitor whether specific services are the bottleneck. Consider increasing loop intervals as a temporary mitigation if services cannot complete in time.
