Oracle iPlanet Web Proxy Server 4.0.14 Performance Tuning, Sizing, and Scaling Guide

Keep-Alive Flushes

The number of times the server had to close a connection because the total number of connections added exceeded the keep-alive maximum connections setting. The server does not close existing connections when the keep-alive count exceeds the maximum connection size. Instead, new keep-alive connections are refused and the number of connections refused count is incremented.
