I've done a similar query below though the MATCH has a more specific pattern rather than querying all nodes. If I only return A or B the query works fine, but with A and B the database will lock on "Executing query.." then return "Unknown error". If the query is a bug let me know and I'll post it to Github.
Neo4J Browser then drops a red bar over the console stating "Disconnected from Neo4j. Please check if the cord is unplugged", this will display for a few moments, disappear and come back repeatedly. Looking at my Task Manager, Neo4j Community CPU was running at 70-100%, I'm assuming I caused a loop with the only way to stop it by restarting the DB. Stopping the server with 'neo4j-community.exe' shut the server down but CPU usage still remains at around 75(3 of 4 CPU cores?), RAM usage stopped growing, was at 4.4GB, Starting the server again RAM consumption continues to grow with no user action, Disconnected notification appears again. By killing 'neo4j-community.exe' via Task Manager, starting the process again RAM usage stays steady at 180MB after starting the server. No disconnected notification, 0 CPU usage with no user action. I was expecting a list of nodes from the MATCH and a variable(B) to store the first result in. I've provided a simplified example of the query that causes the problem: MATCH (A) WITH A, head(collect(A)) as B RETURN A, B -- You received this message because you are subscribed to the Google Groups "Neo4j" group.
