Hmm...

What version of Webalizer do you have? Where did you get it? What RaQ do you have? 3 or 4? Also, did you install the "/home log patch"?

Try deleting all
/home/sites/*/logs files (* means all logs for virtual sites - be sure to TURN OFF httpd for this) and then delete the logs...
Also delete /etc/httpd/logs
all logs there...

Restart apache... Maybe that might do the trick...
Let me know, and post what RaQ and Webalizer you use...
