vi /etc/security/limits
this will change on reboot and become prmanent but to change it on the fly
with out rebooting use the following
chuser rss=<value> <username>
chuser fsize=<value> <username>
chuser data=<value> <username>
After reboot this will revert back to what is in /etc/security/limits
+===========================================
Other problems with file system and sizes may be that you have to create an enhanced o ( or big file enabled filesystem ) but you will have to look at what you have set in fs
