Is the netstat output a typo?  With MaxClients 1000 and the default
ListenBackLog of ~500, you should have started refusing connections
long ago.

Likely most of them are TIME_WAIT. Those are not connected any more, but to many of them make the TCP connection hash slow on many platforms.

If the OPs output is like mine, he can get a better statistics via:

netstat -tan | awk '/:80 / {print $NF}' | sort | uniq -c
