Dear Managers,

A user tried to use an array with size > 1GB in a Fortran program. The
program fails with

prompt> memtest
1183:memtest: /sbin/loader: Fatal Error: cannot map Main

I think I have to tune the kernel parameters, but which one is it.
I'm using DU 4.0D with following parameters:

8< ---------------- excerpt of /sys/conf/MACHINE -------------------- >8
dfldsiz 536870912
maxdsiz 2147483648
dflssiz 2097152
maxssiz 33554432
cpu "DEC2100_C500"
maxusers 128
config vmunix swap generic
8< ---------------- -------------------- >8

TIA
Gerhard
