Neo4j碰撞断管错误

我的Neo4j服务器崩溃（2.0.1版）。我使用py2neo运行了一个批插入，它突然崩溃了

查看日志，我唯一发现的是一个反复出现的错误：

这是控制台中的最后一条消息，我在所有日志中都找不到任何其他错误

编辑：

现在我可以重新创建崩溃。我正在运行以下代码：

    qStr = "match (it:Item) match (it)-[r]->(pr:Property) where NOT has(r.rank) return r"
    query = neo4j.CypherQuery(self.graph_db,qStr)
    count = 0
    for record in query.stream():
        count =count +1
        self.batch.set_property(record[0],"rank", 10)
        if count > 500 :
            self.batch.submit()
            print record[0]
            count = 0
            self.batch.clear()

---

它总是在1000条记录之后崩溃。误差与上述相同。我有neo4j-gc.log-没有什么特别的，没有声明错误。

这看起来服务器没有响应。您的批量请求有多大？你有它的代码吗？你能可靠地重新创建它吗？

批处理请求，由50个节点和500个rel组成，每个批处理，总共100批。我再次运行了它，它没有任何失败，所以我并没有不安的方式来重新创建它。但是，它昨天两次以同样的方式崩溃，没有任何明显的原因
