ulimit is a bash builtin command. You can limit resource use with that; change the shell script that runs the process. Add ulimit -H (hard) with a -d [size] if the data segment needs to be limited, or overall working set size with -m [size]. [size] is a number of 1024 byte chunks.

I need to have this be a system wide limit, the users are running the ones running the process, I dont really want to modify their scripts.

Put it in /etc/profile or whatever you have setup to run during login.
