Are you adding all your data in one big transaction? Because all such additions will be kept in memory until the transaction is committed, see http://wiki.neo4j.org/content/Transactions#Big_transactions for more information. You will need to commit your transaction on a regular basis to avoid that. I'm afraid I don't know the Python bindings enough to write an example here though...
