[Samba] not understanding nmbd.log entry

[Matt Easton]

Hi, I recently had to replace a bad hard drive in my Redhat (RHEL ES3) 
system.  So I reinstalled the OS and manually moved the samba files 
over.

Seems to mostly work ok, but I see a quasi-duplicate entry in the nmbd 
log file after the 4am cronjob restarts samba.

The first entry for 2005/07/10 looks right to me.  The second entry, 
referring to UNICAST_SUBNET--- what's that about?  And why is Master 
Browser unknown on 127.0.0.1?

testparm says my smb.conf file is ok, and in any case, it is unchanged 
from before.
