On one of my servers when I type netstat -n I get a huge output, something like 400 entries for httpd. The bandwidth on the server isn't high, so I'm confused as to what's causing it. I'm suspecting an attack, but not sure.

Intermittently, the web server will stop responding. When this happens all other services such as ping, ftp, work just normally. System load is also normal.

The only thing that isn't normal I think is the "netstat -n" output.

Can you guys take a look and see if there's something I can do? I have APF installed, but not sure what rules I should put into place to mitigate the problem.

Btw, I'm running CentOS 5 Linux with Apache 2.
