Logging -> Completely separating RT from Apache default

I’ve missed something somewhere and I’m not sure where… some logging is
still slipping through to my default Apache error_log.

RT_SiteConfig.pm:

Set($LogToSyslog, ‘’);
Set($LogToFile, ‘info’);
Set($LogDir, ‘/opt/rt3/var/log’);
Set($LogToFileNamed , ‘rt.log’);

Apache VHost Config File for RT:

<VirtualHost *:80>
ServerName rt.example.com
ServerAlias rt
DocumentRoot /opt/rt3/share/html

CustomLog /opt/rt3/var/log/apache-vhost-customlog common
ErrorLog /opt/rt3/var/log/apache-vhost-errorlog

……

Yet, the runtime [error] and [info] messages are going into
/var/log/httpd/error_log (default for apache).

e.g.:
[Mon Feb 23 12:54:09 2009] [error]: WebRT: No ticket specified
(/opt/rt3/share/html/Elements/Error:82)

and

[Mon Feb 23 13:08:12 2009] [info]:
rt-3.8.2-12345-1234567890-111.1111-1-1@example.com #111/26875 - Scrip
7 On Correspond Notify Other Recipients
(/opt/rt3/bin/…/local/lib/RT/Action/SendEmail.pm:301)

What have I missed?
