Just to be sure, you'll want more than 2GB of RAM on a production machine for your Cassandra node.

Was it installed from a tarball or through a package manager of some sort? Did you change the data and commitlog directories before or after you tried troubleshooting startup problems? The cassandra.yaml and log4j-server.properties file would be useful if you can attach that for me.
