[Samba] nmbd using 80-90% cpu for name reg from phantom

nmbd is using a lot of cpu:

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

22681 root 20 0 10080 1520 1084 R 99.0 0.3 146:30.78 nmbd

log.nmbd logs 30-40 messages per second::

[2008/05/17 12:56:41, 0]
nmbd/nmbd_incomingrequests.c:process_name_registration_ request(212)
process_name_registration_request: unicast name registration request
received for name SEC00159925E132<00> from IP 10.10.10.102 on subnet
UNICAST_SUBNET. Error - should be sent to WINS server
[2008/05/17 12:56:41, 0]
nmbd/nmbd_incomingrequests.c:process_name_registration_ request(212)

UNICAST_SUBNET. Error - should be sent to WINS server

nmbd is not set up as a WINS server.

The DHCP server only hands out addreses above 10.10.10.120, so .102
should not exist, and, in fact, 10.10.10.102 can't be found:

ping 10.10.10.102
PING 10.10.10.102 (10.10.10.102) 56(84) bytes of data.
From 10.10.10.2 icmp_seq=2 Destination Host Unreachable

So, why does nmbd chew up so many cpu cycles dealing with this.

And, any clue where 10.10.10.102 is??

I don't need a WINS server.

Well, turning on wins support solved it. So even if I don't need it,
I'll have it. Odd that it's required.

No idea what it did with the phantom.
