slight mod_perl problem
Ok, it seems that my startup.pl is being run twice on server start.
Startup init running
startup.pl - loading templates into memory
--- Loaded template file user_reg.tmpl

Anyone have an explanation as to why this is happening, I have no hair
left due to trying to figure this one out.
Thanks for your help,
Jamie

Since configuration scripts can include other scripts, you probably have
more than one other script that includes startup.pl, or more than one
script that includes something that includes startup.pl, or other such.
This is a commonly encountered situation in programming.
What you need to do is scan your other relevant config files to look for
multiple includes of another file and remove one. Or, if this isn't
feasible, then there may be some conditional that you can use to check if
you already ran a script, and then not do it again.
Of course, there could be a different reason that this is happening...

I have it on as well, and it was only called once. I'm running
mod_perl as a DSO, though. Perhaps that's the difference?

could be he has PerlFreshRestart On, in which case it would be called
twice.

I just tested it also, and the startup script is run exactly once.
This is on: Apache/1.3.14 (Unix) mod_perl/1.24_02-dev

I've just tested it -- it's not.
The I<startup.pl> file and similar loaded via C<PerlModule> or
C<PerlRequire> are compiled only once. Because once the module is
compiled it enters the special C<%INC> hash. When Apache
restarts--Perl checks whether the module or script in question is
already registered in C<%INC> and won't try to compile it again.

startup.pl does not get repeated on a restart. However it will when
started with ./apachectl start. I have never encountered this with Apache
1.3.12 or 13.

See
http://perl.apache.org/guide/config.html#Apache_Restarts_Twice_On_Start
Apache restarts twice indeed, but it shouldn't rerun the startup.pl since
it's already require()d and in %INC.
