Yes and no.  The code looks like this:

use lots of modules;
exit(&main);
sub main {
	my $pageOBJ = Template->new({    ABSOLUTE => 1,
		START_TAG => quotemeta('[*'), END_TAG => quotemeta('*]') });
	my $in = new CGI;
	do stuff...
	my $cached_page = &getFilename($in);  # passing the CGI object
	do stuff...
	$pageOBJ->process($cached_page, $vars) || die $pageOBJ->error(), "\n";
}

sub getFilename {
	if requested file is old or not cached then (re)build the file
		my $pageOBJ = Template->new({ABSOLUTE => 1, OUTPUT => $file});
		do stuff...
		$pageOBJ->process($page, $vars) || die $pageOBJ->error(), "\n";
	}
	return $file;
}

So the code is fairly structured, and I can't see the "break" you mean, but I 
can see how that would cause a problem.

However I still think the fact that I have three Template objects open during 
the running of this script could be a problem.

But if it could be the CGI being a problem then perhaps the httpd.conf can help?

PerlSwitches -I/usr/local/lib/perl5/site_perl/5.8.0/i386-freebsd/Apache2
PerlOptions +SetupEnv
PerlModule Apache::compat
PerlModule Apache::DBI
PerlModule Apache::AuthDBI
PerlModule CGI
PerlInitHandler Apache::Reload
PerlSetVar ReloadAll Off
<VirtualHost CLIENT>
  <Directory /web/client>
   Options +ExecCGI
   PerlOptions +ParseHeaders
   <Files ~ "\.(pl)$">
    SetHandler perl-script
    PerlHandler ModPerl::PerlRun
   </Files>
  </Directory>
</VirtualHost>

Does loading CGI as a module cause problems?  I read that it's actually a "slow" 
module to load, and so doing this helps speed it up.

Thank-you,

Tosh
