Neo4j batchInserter异常

Question

我有Batch Inserter在Neo4j中构建数据模型，但我在节点之间创建relationship时遇到错误，而不是所有relationships，而是其中一些org.neo4j.kernel.impl.nioneo.store.InvalidRecordException: RelationshipRecord[someID] not in use 。

以下是例外：

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

并且它被抛入该行：

org.neo4j.kernel.impl.nioneo.store.InvalidRecordException: RelationshipRecord[454889] not in use

任何帮助将不胜感激..

您是否在批量插入中使用多个线程？如果是这样，事情就会破裂。我在堆栈跟踪中发现了一个ThreadPoolExecutor，这就是我问的原因。
