Neo4j batchInserter exception

Question

I have a Batch Inserter that build a data model in Neo4j, but I have an error on creating relationship between nodes, not all relationships but some of them.

Here's the exception:

org.neo4j.kernel.impl.nioneo.store.InvalidRecordException: RelationshipRecord[someID] not in use

and it's thrown in that line:

long relId = inserter.createRelationship(node1ID, node2ID,RelTypes.My_REL,node1TOnode2RelProps);

Any help would be greatly appreciated..

Here's the stacktrace

Answer 1

Are you using multiple threads in your batch insertion? If so then things are going to break. I spotted a ThreadPoolExecutor in the stack trace so that's why I ask.
