I am new to Neo4j and I started playing with DocGraph (https://dl.dropboxusercontent.com/u/57740873/neo_doc_v1.tar.gz) . It is a 1.8 database describing referrals between physicians. The database is loaded to Neo4j but when I try to do any query from the webrowser the server crashes. I checked the log and here is the output:
