Have you looked at the output of limit/ulimit? In addition to the file 
descriptors limit that is mentioned in the FAQ 
http://svn.orcaware.com:8000/repos/trunk/orca/FAQ at item 2.3, you can 
also adjust the datasize or the max amount of RAM the process can 
malloc(). You should used "ulimit -d" for sh variants and "limit 
datasize" for csh variants of user shells. On my system, limit reports 
the following, allowing me to allocate memory until swap space is 
exhausted.

ra:~> limit
cputime         unlimited
filesize        unlimited
datasize        unlimited
stacksize       8192 kbytes
coredumpsize    4096 kbytes
vmemoryuse      unlimited
descriptors     256
ra:~> limit -h
cputime         unlimited
filesize        unlimited
datasize        unlimited
stacksize       unlimited
coredumpsize    unlimited
vmemoryuse      unlimited
descriptors     1024
