'out of memory' errors

i am trying to us a perl application that handles large files (.5GB) in scalar
variables. when i try to 'slurp' one of these files into a variable
(e.g., '$_ = `cat filename`) i get an out of memory error. (same for '@var =
<FH>') initially, i ran the script without any memory limits. that was fine
except the process would freeze the rest of the system. i dealt with this
problem by setting limits for myself in /etc/security/limits.conf as follows;
kloro hard rss 256000
kloro hard memlock 256000
kloro hard as 768000
now, tho' i get 'out of memory' errors.
is there not some way to get linux to use swap space when physical memory is
exceeded?
thanks,
tom arnall
