samba - Nov 2003 - nmbd: No subnets to listen to. Shutting down....

Morning,

I'm running the HP version (CIFS) of 2.2.8a on a HPUX server. This morning
a user complained that they could not connect to their share. What I found
in the log.nmbd is:

   [2003/11/21 10:39:36, 0] nmbd/nmbd.c:(256)
     reload_interfaces: No subnets to listen to. Shutting down...

When I checked the log file, I found out that this has occured a few other
times in the past three months.

Any ideas on what this error actually means? And is there a way to prevent
the shutdown? Work around?

Thanks

Greg
