Hi, I'm having some trouble using Neo4J in Ubuntu 11.04 Linux OS. The program
I've writen works fine under Windows 7 but when I tried to run it at Linux
I'm experiencing some problems:
org.neo4j.kernel.impl.nioneo.store.PersistenceWindowPool logWarn
WARNING:
[/home/fmagalhaes/Coppe/GraphBD/CineastDB/neostore.propertystore.db.index]
Unable to memory map
Oct 20, 2011 6:59:17 PM
org.neo4j.kernel.impl.nioneo.store.PersistenceWindowPool logWarn
WARNING:
[/home/fmagalhaes/Coppe/GraphBD/CineastDB/neostore.propertystore.db.index.keys]
Unable to memory map
as soon as my program reaches these line of code:
GraphDatabaseService sourceDb = new
EmbeddedReadOnlyGraphDatabase("/home/fmagalhaes/GraphDB/CineastDB");
GraphDatabaseService targetDb = new
EmbeddedGraphDatabase("/home/fmagalhaes/GraphDB/DistDB");
After this warning message the program starts, but at a later point I keep
receiving these error messages:
WARNING:
[/home/fmagalhaes/GraphDB/CineastDB/neostore.propertystore.db.strings]

Can someone help me with this problem? Thanks!
