It's normal. Your code is running twice, but stderr is closed by Apache 
during the restart's config and open_logs phases. it's reopen for the 
post_config phase.

In Apache 2.0 one should avoid running startup code at config phase, 
unless it's httpd.conf-specific. Instead post_config should be used. replace:

PerlRequire with PerlPostConfigRequire
http://perl.apache.org/docs/2.0/user/config/config.html#C_PerlPostConfigRequire_

You will need the latest dev version to get this new feature:
http://perl.apache.org/download/source.html#Development_mod_perl_2_0_Source_Distribution

I plan to write more docs explaining the issue.

Your version is *very* old (like 2+ years old), but this particular issue 
will be still there. It's an Apache issue/feature.
