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 default for this parameter is set very high (10,000) as Samba uses only one bit per unopened file. 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 = 10000
