Hi,
firstly I used the numbers of 9 bytes * number_of_nodes and 33 bytes *
number_of_relations for the neo.props configure, but it doesn't work.
After that I tried with my actual configuration:
neostore.nodestore.db.mapped_memory=180G
neostore.relationshipstore.db.mapped_memory=6000G

Around 57.000.000 nodes and 322.000.000 relationships. Now I'm trying
I see that you're using an older version of Neo4j. Have you tried using 1.0?

http://neo4j.org/download
Maven
groupId: org.neo4j
artifactId: neo4j-kernel
version: 1.0
...and at first glance I don't see any direct problem with your code.

One more thing... how much heap have you given the JVM? You control
how much RAM your JVM gets with the -Xmx option to the java command.
F.ex:
java -Xmx10G -cp .
Please see more information regarding performance and tweaking at

Yes I give 64 GB and only 60 GB in diferent executions.
