invalid user 'www'

[GNorm]

Hello all,

I am having a problem with apache. When I try to start or restart apache 
using apachectl i get the following message.

Limits:  invalid user 'www'
Usage:  [a list of switches]
httpd: bad user name www

When I do apachectl configtest I get the same message.

I have looked at /etc/group, /etc/passwd, and /etc/master.passwd for 
www. The user is there. Any help will be appreciated.
