@Neo
Thanks Neo for Replying. but My question is all of my configuration are the same. 1Gb ram and 17 to 35GB HD. some of them are running absolutely fine. More over Apache is a light weighted application....if we can tune it proper than it should not take this much of memory.[COLOR="#738fbf"]

apache::singleton
Apache::Singleton(3pm) User Contributed Perl Documentation Apache::Singleton(3pm)
NAME
Apache::Singleton - Singleton class for mod_perl
VERSION
version 0.15
SYNOPSIS
package Printer;
# default:
# Request for mod_perl env
# Process for non-mod_perl env
use base qw(Apache::Singleton);
package Printer::PerRequest;
use base qw(Apache::Singleton::Request);
package Printer::PerProcess;
use base qw(Apache::Singleton::Process);
DESCRIPTION
Apache::Singleton works the same as Class::Singleton, but with various object lifetime (scope). See Class::Singleton first.
OBJECT LIFETIME
By inheriting one of the following sublasses of Apache::Singleton, you can change the scope of your object.
Request
use base qw(Apache::Singleton::Request);
One instance for one request. Apache::Singleton will remove instance on each request. Implemented using mod_perl "pnotes" API. In
mod_perl environment (where $ENV{MOD_PERL} is defined), this is the default scope, so inheriting from Apache::Singleton would do the
same effect.
NOTE: You need "PerlOptions +GlobalRequest" in your apache configuration in order to use the Request lifetime method.
Process
use base qw(Apache::Singleton::Process);
One instance for one httpd process. Implemented using package global. In non-mod_perl environment, this is the default scope, and you
may notice this is the same beaviour with Class::Singleton ;)
So you can use this module safely under non-mod_perl environment.
