Hi,

As a workaround you can disable the following lines in the web-server config from apache, probably under /etc/apache2/conf.d/otrs

#    <IfModule Apache2/Reload.pm>
        # Apache::Reload - Reload Perl Modules when Changed on Disk
        PerlModule Apache2::Reload
        PerlInitHandler Apache2::Reload
#    </IfModule>
    PerlModule Apache2::RequestRec

Kind regards
