I suspect you are seeing a false positive from the consistency check run during an incremental. There is an option to not do the check ( -verify false ) and the do a full consistency check on the backup store.
Full consistency check tuning and more details of these options are covered in Mark's blog: ``` http://www.markhneedham.com/blog/2014/01/22/neo4j-backup-store-copy-and-consistency-check/ ``` If you could provide the error/trace from your experience it will help with the repro. It would also be good to know if it is not a false positive i.e. if the full check identifies an issue. Thanks, John @ Neo4j.
