[Samba] nmbd dump_workgroups()

[Ngo, Toan]

Every day, I get this error message.  It's always around 4:02AM.

This occurs on 3 different smb servers at the same time.
Two are running samba-3.0.14a-2 (one in Active Directory, one isn't)
One is running samba-3.0.22-1.fc5 (not in Active Directory)

Any ideas?
