Sorry about the delay posting this I held off posting as I hoped I
would get a few more answers. In the end I got two. So thanks to
Richard Bremose and Marco Luchini
Richards reply
We had a similar problem with a model into which a large matrix was
defined. Try increasing the per-proc-data-size as well:
proc:
per-proc-data-size=1024000000
$ limit
cputime 6:00:00
filesize unlimited
datasize 1000000 kbytes
stacksize 2048 kbytes
coredumpsize unlimited
memoryuse 377224 kbytes
vmemoryuse 1048576 kbytes
descriptors 4096
I put our limit upto 4GB and still had no joy :(

up, but the loader seems to require more resources than it used to.
Usually this is solved by unlimiting the resources for the controlling
shell:
csh> unlimit
and some other version for the other shells - see the shell man
pages. If
the shell unlimits aren't enough you might have to increase the kernel
limits but I've never seen that happen for "normal" code.

I had tried this before and had still the same error
Oh well Ill keep bashing away till I sort it.
