Please try not to cross post on several channels. Thanks! Neo4j node id's are record id's so if you provide it with a high enough rercord number it will create all those intermediate empty records on your disk.
If you have a slow disk, and perhaps not configured memory mapping then it can take a while to write out all the data. So in your case it will create 1.39 billion empty records to insert your second node. You should refrain from controlling node-id's externally if you are not totally sure you know why you want to do it.
