backhand stopping apache restart

Got a strange error here.

At midnight, we rotate our log files, and do an 'apachectl graceful' 
restart, however, something is wrong as apache doesn't come back. We see 
this in the log file:

Syntax error on line 675 of /usr/local/apache/conf/httpd.conf:
Invalid command 'Backhand', perhaps mis-spelled or defined by a module 
not included in the server configuration

Any clues?
