Script to leak file handles
This is a strange one.

We have an issue where our system is leaking SCTP file handles. There are people working on this and in the mean time we have a monitoring script that alarms when we need to perform actions to manually clear them. For testing purposes I want to write a script that purposfully leaks file handles and fast (leaks about 4000 in a few minutes). The problem is I have absolutely no idea how to do this or where to start and (surprisingly) it is not something people commonly want to do so the internet has not been helpful.

Does anyone know if it is possible to write a script (ksh Solaris) to leak file handles?
If so, would anyone be able to give me some pointers to get me started?

Just to let you know that I found it was easier to fake the output of netstat to make it look as if more file handles were in use than actually were, so I no longer need help with this. Thanks

NAME

       mrtg-webserver - hints for web server configuration

SYNOPSIS

       If you want people to actually see the results of your network monitoring efforts you will need a webserver.

       This document lists some configuration hints for webservers. Contributions welcome.

APACHE

   Configuring mod_expire
       A big issue with mrtg monitoring data is the expiry time.  All these nice graphs you can create are only valid for a short time.  If you do
       not take special action some webbrowsers will not notice this and you may end up with people seeing old data because of caching issues.

       The apache module mod_expire allows you to setup special expiry properties for individual file.

       Here is an example for how this may look for an mrtg web directory.  The configuration directives can be stored into a .htaccess file.

	############################################################
	# Example .htaccess for use with apache-1.2 and mod_expire.
	# (mod_expire come with apache-1.2 but you have to explicitly
	# activate it when compiling the httpd ...)
	#############################################################
	#
	<Files "*-day.png">
	ExpiresActive On		  # enable expirations
	# five minutes
	ExpiresDefault M300
	</Files>

	<Files "*-week.png">
	ExpiresActive On
	ExpiresDefault M1800
	</Files>

	<Files "*-month.png">

	<Files "*-year.png">
	ExpiresActive On
	ExpiresDefault M86400
	</Files>

	<Files "*.html">
	ExpiresActive On
	ExpiresDefault M300
	</Files>
