Thanks to those who responded.

	Look at the per_proc_data_size, per_proc_stack_size, and
per_proc_address_space and adjust these accordingly.  This can be done by
using dxkerneltuner or modifing the sysconfigtab file.  To see what these 3
attributes does fully see the man page (man sys_attrs_proc)

In the "proc" section, it's per-proc-data-size and max-per-proc-data-size. 
----
proc:
        max-per-proc-address-space = 2147483648
        per-proc-address-space = 2147483648
        max-per-proc-data-size = 2147483648
        max-per-proc-stack-size = 268435456
# Belonis made these kernel variable modifications to make 2GB RAM usable
#    by a single process
# and in response to sys_check suggestion
vm:
        vm-mapentries = 1000000
        vm-maxvas = 2147483648
        vm-vpagemax = 131072
I did this stuff in response to this ancient posting on this mailing list.
