Have not upgraded the gen2 yet. No known work around. restarting samba does not fix the problem. I also noticed that smbd creates a new process every minute. If you look at the sockets listed in /etc/samba/msg.sock. You will see that a new socket is created every minute. The name of the socket is the pid of the new smbd process.
I posted a email on the samba technical group asking about the msg.sock.
