I think it is a normal startup message by Apache just showing the command line that started the instance. I noticed the the ctl.sh script was looking at whether the file "disable-banner" was present, so as a test I just removed that file and restarted apache and it now just shows:
AH00094: Command line: '/opt/trac-1.2.2-1/apache2/bin/httpd.bin -f /opt/trac-1.2.2-1/apache2/conf/httpd.conf'
So I am taking it to be a normal message in the log. I should have googled the AH00094 flag.
