[Samba] Mac Clients Disconnect with: source3/smbd/service.c:1050(close_cnum) closed connection to service data

[torch]

Am curious why you have protocol_vers_map=4 in your nsmb.conf - that enables only SMB 3 (man nsmb.conf);  I use protocol_vers_map=6 (enables SMB 2/3).  You may want to also include port445=no_netbios in your nsmb.conf.  My Mac connections basically stay connected continuously unless I actually disconnect them.
