KeepAlive Misconfiguration Exhausts Connectionswarning

KeepAliveTimeout set too high causes idle connections to consume worker threads/processes, reducing effective concurrency. KeepAliveTimeout set too low forces excessive TCP handshakes, increasing latency. Optimal values depend on traffic profile: APIs need 2-5s, static content 5-15s.
