Hi Michael, Thanks for the tip. I totally missed the comment signs :-)
However I removed them and still the server crashes. Also, could you be more specific which lines of the neo4j.properties do I have to change ? I see the following lines: # Default values for the low-level graph engine #neostore.nodestore.db.mapped_memory=25M #neostore.relationshipstore.db.mapped_memory=50M #neostore.propertystore.db.mapped_memory=90M #neostore.propertystore.db.strings.mapped_memory=130M #neostore.propertystore.db.arrays.mapped_memory=130M Thanks, Alex On Wednesday, January 22, 2014 8:00:53 PM UTC-5, Michael Hunger wrote: > > You have to remove the comment signs (#) at the beginning of the lines in > the config file. > > # Initial Java Heap Size (in MB) > wrapper.java.initmemory=6400 > > # Maximum Java Heap Size (in MB) > wrapper.java.maxmemory=6400 > > I assume you have JDK 7_21 or _25 running which consequently only > allocates a tiny bit of memory. > > You should also look into conf/neo4j.properties and adapt the memory > mapping setting to roughly match the store-file sizes in data/graph.db > Usually this works automatically, but just in case :) > > Cheers > > Michael > > > > On Wed, Jan 22, 2014 at 11:19 PM, Alx <[email protected] <javascript:>>wrote: > >> I am new to Neo4j and I started playing with DocGraph ( >> https://dl.dropboxusercontent.com/u/57740873/neo_doc_v1.tar.gz) .
