This is a very advanced smbd 8 tuning option to improve the efficiency of the granting of oplocks under multiple client contention for the same file. In brief it specifies a number, which causes smbd 8not to grant an oplock even when requested if the approximate number of clients contending for an oplock on the same file goes over this limit. This causes smbd to behave in a similar way to Windows NT. DO NOT CHANGE THIS PARAMETER UNLESS YOU HAVE READ AND UNDERSTOOD THE SAMBA OPLOCK CODE. 2
