Hi Peter,
I don't understand much your question. However, in my Restlet application I have a logging service using Java log to record all processes in my app. My problem is that I upload 20 ontologies and after serveral ontologies the Neo4J stops responding my REST request. It seems busy with some index lookup process. Consequently my app throws a NoHttpResponseException: The target server failed to respond. I'd like to see what causes the problem inside Neo4J. Unfortunately both messages.log and neo4j.x.x.log do not show run time processes. BTW, when I start up the server the neo4j.x.x.log shows INFO: Server started on [http://localhost:7474/] Nov 9, 2011 10:22:22 AM org.neo4j.server.logging.Logger log WARNING: java.lang.IllegalArgumentException: Bad sample time: 1320862942.
