Great (the no problems part) ! Can you attach with gdb to this error
message and get a backtrace when it occurs please ?




I'd need some pointers, I'm not all that familiar with gdb, and there is no way to stop on the error.  NMDB still runs after displaying this; so, I don't think a back-trace will help find it when I kill the process.

It looks as though it may be trying to copy the allowable IP addresses into a structure that only has space for 15 characters.  The ip [] ends up being in the config file 
[root at beta samba]# cat smb.conf | grep
   interfaces =
