The limit of 384 maxusers for auto configuration was only imposed on 32-bit systems. Currently its grow slowly above the 384 mark. maxusers number This optional directive is used to configure the size of some kernel data structures. The parameter number can be 0 (the default) or an integer greater than or equal to 2. A value of 0 indicates that the kernel should configure its data structures according to the size of available physical memory. If auto configuration is requested, the kernel will set this tunable to a value between 32 and 384. As explained in tuning(7), this tunable can also be set at boot time using loader(8).
