Description of problem:
nmbd dies a random interval after starting. Usually when a windows
client tries to browse the net.

The samba server is the local browse master, and a domain member
server, but not a PDC. The PDC is on another subnet, outside of a
firewall. Error does not occur when the samba server is not the local
browse master. 

iptables is stopped and SELinux is disabled. Problem still occurs.

The nmbd log states :
[2005/03/08 11:32:34, 0] nmbd/nmbd.c:main(669)
  Netbios nameserver version 3.0.10-1.4E started.
