    First question, I would have, is what do you mean by you create multiple
server instances for samba w/systemd.  Then you get nmb not working 
with, I assume, some of the server instances (on the same machine)?

    That's my 1st confusion: what do you mean by saying that you create
multiple server instances?  If you are starting the full "server" for samba
multiple times, wouldn't "nmbd" also be started multiple times?  If they are
on the same machine, wouldn't they conflict with each other if they were all
attempting to listen at the same address? 

    Depending on random timing, any given instance of nmbd might fail if
another instance had already been started.

    Is this what you meant?

As for the you included, have you checked with 'netstat' to see
what is already connected at nmbd's address? 
I.e. on my machine:

>  sudo netstat -pul |grep nmbd|sed -r 's/ {8}/  /g'

udp  0      0 broadcast.sc:netbios-ns*         1586/nmbd    
udp  0      0 Ishtar:netbios-ns*         1586/nmbd    
udp  0      0*         1586/nmbd    
udp  0      0 broadcast.s:netbios-dgm*         1586/nmbd    
udp  0      0 Ishtar:netbios-dgm*         1586/nmbd    
udp  0      0*         1586/nmbd

(re: netstat, -u=udp, -l=include-listening, -p=showprog(requires root))
I see 1 copy of nmbd(pid=1586) listening to services 137(netbios-ns)
and 138(netbios-dgm).
