Thanks for your reply Dave I use strict, warnings on, the objects are created within a sub using 'my'. I stripped down the script to see what was going on but to no avail.

#!/usr/bin/perl -w

use CGI;
use Session;
use Community;
use CGI::Carp;



main();

sub main {
 my $query = new CGI;
 my $uri = 'www.moonfruit.com';
 setup($uri, $query);
}


sub setup {
    my ($uri, $query) = @_;
    my $dbh = db_connect();

    my $session= new Session($dbh, $query, "guest", $uri);
    my $community = new Community($session);

print $query->header();
return;
}

So the objects should go out of scope once the sub has finished. However as I mentioned they don't automatically get 'destroyed'. I know this as the DESTROY method of the objects are not called, they are however called when I stop the server.
