Server has more TIME_WAIT connections in Apache(port 80)
Server has more TIME_WAIT connections in Apache(port 80) Hi,
My webserver has 16GB of RAM and CentOS 5.5, Apache 2.2.3, It's shared webserver used of for webhosting. I have optmized the server as :
Code:
<IfModule prefork.c>
StartServers       8
MinSpareServers    10
MaxSpareServers   20
ServerLimit      2150
MaxClients       2000
MaxRequestsPerChild  8000
</IfModule>

Timeout 90
MaxKeepAliveRequests 100

Server is not using Worker MPM, however just assign the following values.
Code:
<IfModule worker.c>
StartServers         8
MaxClients         2150
MinSpareThreads     25
MaxSpareThreads     75
ThreadsPerChild     25
MaxRequestsPerChild  8000
</IfModule>

More number of TIME_WAIT Connections on server still exists.

Code:
[root@server ~]# netstat -an|grep ":80"|awk '/tcp/ {print $6}'|sort -nr| uniq -c
 1681 TIME_WAIT
      2 SYN_RECV
      4 LISTEN
      3 LAST_ACK
      7 FIN_WAIT1
      6 ESTABLISHED
      3 CLOSING

[root@server ~]# netstat -tan |grep :80|grep TIME_WAIT |wc -l
1776

Server Load Avg: 2.36, 2.45, 2.79

Please help me how to reduce the TIME_WAIT connections.

Thanks,
Jay

svnweb-server

SVNWEB-SERVER(1p)					User Contributed Perl Documentation					 SVNWEB-SERVER(1p)

NAME

       svnweb-server - simple webserver for SVN::Web

SYNOPSIS

	 svnweb-server [--root DIR] [--port PORT] [--net-server Net::Server]

DESCRIPTION

       svnweb-server is a webserver that runs SVN::Web.  It's an easy way to use SVN::Web without having to set up Apache (or any other web
       server).  The tradeoff is that the server is very simple.  But for light use then it may be perfectly acceptable.

OPTIONS

       --root DIR
	   The directory in which you ran "svnweb-install".

	   Optional, defaults to ".".

       --port PORT
	   The port the server should listen on.

	   Options, defaults to 8080.

       --net-server Net::Server
	   The Net::Server subclass to use to create the server.  A single, non-forking server is created by default.  Other types of server can
	   be created by giving the correct Net::Server subclass.  For example, to use a server that forks to handle each request, use
	   "--net-server Net::Server::Fork".

SEE ALSO

       SVN::Web

BUGS

       This is a simple server.  Accordingly, a few features do not work properly at the moment.

       Redirects
	   SVN::Web::Browse will redirect the client if the URL is missing a trailing "/".  That redirection does not work with this server.
	   That's not an issue for any URLs generated by SVN::Web, but may be an issue for URLs that are entered by hand.

	   This will also affect SVN::Web::List's "redirect_to_browse_when_one_repo" option.

       cgi_class
	   The "cgi_class" declaration (if any) in config.yaml is ignored.  CGI is always used as the CGI class.

       Please report any bugs or feature requests to "bug-svn-web@rt.cpan.org", or through the web interface at
       http://rt.cpan.org/NoAuth/ReportBug.html?Queue=SVN-Web <http://rt.cpan.org/NoAuth/ReportBug.html?Queue=SVN-Web>.  I will be notified, and
       then you'll automatically be notified of progress on your bug as I make changes.
