could be a mixed-up (strange) configuration.
About any 10 minutes the script
/usr/local/samba/sbin/samba_dnsupdate (depends on your install path)
is running, (at some higher debug level) logged like
"Calling DNS name update script"
To get some more information:
1.) stop samba
2.) as root (e.g. sudo) run:
/usr/local/samba/sbin/samba -i -M single -d3
inside a console window
3.) Carefully watch all the outcome
Btw - is your "dns forwarder = 188.8.131.52" (resolver2.opendns.com.)
