Request Queue Buildup Indicates Worker Exhaustioncritical

When NGINX reaches MaxRequestWorkers (or event MPM's equivalent capacity), new requests queue at the load balancer level, causing gateway timeouts even when CPU and dependencies appear healthy. This often manifests as moderate CPU (~50-60%) but rising tail latency and 502/504 errors.
