Thanks everyone, basically, it is normal for a webserver to have TIME_WAIT
connection.  If there is too much, it worth to reduce a /dev/tcp parameter. 

Look a the following link for explanations :

This is what you get when a network connection closes, the particular socket
waits to time out before it is removed.  This is tunable parameter you can
set for tcp.  See this page:
http://www.ashpool.com/doc/mk4mod4/perf_solaris_tcp.php

for more of an explanation.

Hi,

One of my server (E450 2 x UltraSPARC-II@400MHz, 1 Gb RAM Solaris 7 ) is
running Apache 1.3.31 to serve about 10 websites (http and https).

I am trying to understand why there is so much connection in TIME_WAIT state
when I run netstat

[support@ub1981win01]-[/opt/apache/logs]$ netstat -an | grep -c TIME_WAIT
6678
[support@ub1981win01]-[/opt/apache/logs]$

What doest TIME_WAIT means ?
