Increasing maxusers only increases the size of system wide descriptor table. OPEN_MAX chanes the max number of open files per uid. open files per uid never changes via maxusers. CHILD_MAX sets the total number of processes per uid. You will notice that Apache runs and all its related processes run under a single uid, so you will hit the default limit of 40 processes and 64 files per uid quite quickly. The defaults are intended for a general purpose machine where you do not want users using more than their share of the processes and files.
