FreeBSD 4.8: afp3-fileserver (port 7000) showing up in 'netstat -a'

[Albert Everett]

I have a FreeBSD 4.8 (release) system running the following software 
from the current ports tree:

- cyrus-sasl2
- cyrus-imapd2
- mailman
- apache13-modssl
- mod_php4
- squirrelmail
- portsentry
- apcupsd

I'm seeing the following line when I run 'netstat -a':

        tcp4       0      0  *.afs3-fileserver      *.*                  
   LISTEN

In /etc/services, I see:

# grep afs3 /etc/services
afs3-fileserver 7000/tcp   #file server itself
afs3-fileserver 7000/udp   #file server itself
afs3-callback   7001/tcp   #callbacks to cache managers

afs3-remio      7011/tcp   #MR-AFS remote IO server
afs3-remio      7011/udp   #MR-AFS remote IO server

QUESTIONS: What is this afs3-fileserver service? Should it be there 
because of the other software I'm running? Is it part of 4.8? I don't 
see anything related to it that I'm firing up on purpose.
