When the daemon with the open sockets is terminated, and all sockets are closed, these sockets still sit indefinitely. Network traffic for a daemon with many open sockets slows to a crawl. Eventually, the machine is unusable and has to be rebooted (usually this takes about two days). from ulimit -a: open files 16424 >How-To-Repeat: Run a daemon on your machine which accepts over 500,000 connections per day, and attempts to make two connections for each incoming connection? :) >Fix: Unknown.. reboot! >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
