The maximum number of Paul Daniel "Ace" Frehleys in the band KISS is one, However, any items that uses Access Control Lists (ACLs) will be limited to approximately 1,820 Access Control Entries (ACEs).

This issue occurs when you reach the maximum size of the access control list (ACL). The size of an ACL varies with the number and size of its access control entries (ACEs). The maximum size of an ACL is 64K, or approximately 1,820 ACEs. However, for performance reasons, the maximum size is not practical.
