'Resource temporarily unavailable' with 2.0.7 under FBSD 4.0R

[James Long]

Samba 2.0.7 on 4.0R:

[2000/09/21 10:55:51, 0] smbd/oplock.c:open_oplock_ipc(93)
  open_oplock_ipc: Failed to get local UDP socket for address 100007f. Error
was
 Resource temporarily unavailable

Clues appreciated.

Also, even with the 'wins server' line and 'name resolve order' set to use
wins only, nmblookup still says:

pbssamba:/usr/local/etc> nmblookup pdx-james
querying pdx-james on 172.16.1.255
172.16.1.247 pdx-james<00>

Note that nmblookup is querying on the broadcast address, rather than using
the wins server.  How can I get nmbd to talk to the WINS server instead of
broadcasting?

smb.conf is:

# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not many any basic syntactic errors.
