    So  we decreased the max_files_per_process to 800.  This took care
    of the error **BUT** about quadrupled  the IO wait that is happening
    on the machine. It went from a peek of about 50% to peeks of over
    200% (4 processor machines, 4 gigs ram, raid).  The load on the
    machine remained constant.


Sounds to me like you just need to up the total amount of open files allowed by the operating system.
