[otrs] Intermittent 500 errors with OTRS 2.1.5 under Debian ISPConfig

[Reda Sadki]

When I try to use the apache2-httpd-new.include.conf file in conf.d,
Apache won't start unless I comment out these lines.

# Apache::Reload - Reload Perl Modules when Changed on Disk
#PerlModule Apache2::Reload
#PerlInitHandler Apache2::Reload
#PerlModule Apache2::RequestRec

Does this tell you anything about what is wrong with my Perl/Apache
installation that might be causing the 500 errors?
