ModPerl::Util::exit: (120000) exit was called

Afternoon mod_perl'ers,

I am a Perl programmer of 7 years, however this is the first time I have 
come to using mod_perl. In a nutshell I am getting this error:

ModPerl::Util::exit: (120000) exit was called at /path/to/script.cgi

I have a clean install of Ubuntu 10.04, apache2, libapache2-mod-perl2 and the following in apache2.conf:

<Files ~ "\.(pl|cgi)$">
            SetHandler perl-script
            PerlResponseHandler ModPerl::Registry
            Options +ExecCGI
            PerlSendHeader On
</Files>

In my scripts I call exit(); everywhere. However according to the mod_perl website, this shouldn't be a problem (correct me if I am wrong).

I have done the same setup on 3 different servers using the same OS and yield the same error each time!

If anyone has any ideas please let me know. I have searched the internet everywhere for solution, however this problem doesn't seem to be of large.

Kind regards,

James Andrews
