shell limits

Greetings, list.
Here's a quick one.

We've taken delivery of boxes with 256MB in them and Tru64 pre-installed,
and of course the shell resource limits are configured for this much
memory. After installing 2GB more memory, the limits should be re-defined.
Oddly, I cannot get ulimit to effect changes, even as root:

# ulimit -d 250000; ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 131072
stack(kbytes) 8192
memory(kbytes) 2298720
coredump(blocks) unlimited
nofiles(descriptors) 4096
vmemory(kbytes) 4194304
# uname -a
OSF1 flotsam.physics.mun.ca V5.1 732 alpha

(note that the data size limit was not increased from 131072 to 250000.
Also note the great disparity between data & stack size, and memory size).
In fact, I can't effect changes in shell resources at all with ulimit,
down or up, explicit soft limit or not, as root or a plain user;

<28 flotsam /users/csteven> ulimit -S -d 100000; ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 131072
stack(kbytes) 8192
memory(kbytes) 2298720
coredump(blocks) unlimited
nofiles(descriptors) 4096
vmemory(kbytes) 4194304


Thanks for any pointers. Perhaps a kernel reconfig is in order?
parameters to look out for?

Chris
