SUMMARY but still weird: Unable to request >918MByte RAM

Thanks to Anthony A. D. Talltree, alan_at_nabeth.cxo.dec.com and Iwao MAKINO.

I still could not occupy more than 918MB RAM for the process even with
the following parameters set and kernel recompiled and system rebooted.
dfldsiz 4294967296
maxdsiz 4294967296
dflssiz 4294967296
maxssiz 4294967296
maxvas 4294967296

While I looked into the "limit" parameters for csh, I found that I have to
manually set "limit addressspace 4294967296" to get the above setting work
for memory request. However, only default /bin/csh can do this; the tcsh 6.09
didn't recognize the "addressspace" parameter (no matter how many s' are
used, e.g. addrespace, addresspace nor addressspace); and other shells like
/sbin/sh and /bin/sh and BASH could not set this parameter either. Meanwhile,
this parameter could not apply to the shells involked after /bin/csh. So using
the default /bin/csh seems to be the only way to request more than 918MB of
memory on my system. It is solved partially, although it is still weird.

Sincerely

========= THE ORIGINAL QUESTION FOLLOWS ==================
Dear Managers,
	Here I found another problem for my system. Our system has 2GB real
memory and 4.5GB swap. However, we can't request more than 918MByte of 
memory; the system reported that "gmainv1 failure to allocate 121158005".
However, I have set the /etc/sysconfigtab and /sys/conf/$HOSTNAME as previously
discussed in this list, as the following and recompiled the kernel.
Here are the setting for /etc/sysconfigtab
ipc:
        shm-max = 500000000
        shm-mni = 256
        shm-seg = 64
proc:
        max-proc-per-user = 256
        max-per-proc-address-space = 4294967296
        per-proc-address-space = 4294967296
        max-per-proc-data-size = 4294967296
        max-per-proc-stack-size = 268435456
vm:
        vm-maxvas = 4294967296
and the /sys/conf/$HOSTNAME
maxvas          4294967296
dfldsiz         4294967296
maxdsiz         4294967296
dflssiz         2097152
maxssiz         33554432
	So would anyone please show me the indication about what I have left
undone? Thank you very much for your kind help.
