from smb.conf(5)

       max open files (G)

           This parameter limits the maximum number of open files that one
           smbd(8) file serving process may have open for a client at any one
           time. The This parameter can be set very high (16404) as Samba uses
           only one bit per unopened file. Setting this parameter lower than
           16404 will cause Samba to complain and set this value back to the
           minimum of 16404, as Windows 7 depends on this number of open file
           handles being available.

           The limit of the number of open files is usually set by the UNIX
           per-process file descriptor limit rather than this parameter so you
           should never need to touch this parameter.

           Default: max open files = 16404
