Hi there,
I have found a problem with my Samba server 3.0.28. This problem appeared suddenly without
any changes in configuration or server update.
NMBD becomes unresponsive in some minutes after startup with these options enabled:
name resolve order = wins lmhosts hosts
wins server = 172.25.8.86 172.25.8.84
Unresponsive means that it is not possible to connect to server,
nmbd eats full processor power and it is not possible to stop it, only by "killall -9"
This is from log:
[2008/02/21 19:55:15, 0] nmbd/nmbd.c:main(697)
Netbios nameserver version 3.0.28 started.

It works without problems setting it to:
name resolve order = lmhosts hosts bcast
# wins server = 172.25.8.86 172.25.8.84
There is a log. What is strange are the repeating message at the end.

Any ideas what is wrong with WINS?
Thanks!
