My server hosts a fair amount of websites, but nothing crazy. Uptime is usually only 0.5. Anyway, it got real slow, when I finally logged in, uptime was 152, ps -aux showed alot of apache pids, over a 100 (its usually 10 or so), and a netstat -an showed alot of connections to port 80. The odd thing though was all the connections were CLOSED_WAIT Machine is running 6-STABLE, and has 1Gb of memory, with a HT P4 3.2 GHz. And the HT has been turned on, even though its disabled by default. Any ideas as to what is going on? Is there maybe an issue with apache that triggered something, or maybe it was just a random DoS attack. Thanks John
