structr / neo4j数据库已损坏

时间：2016-03-07 05:30:10

标签： neo4j structr

我在拥有2G RAM的Linux VM中使用Structr。我执行了一个查询并崩溃了系统。尝试重新启动平台失败，嵌入式数据库出现以下错误，因此我正在寻找可能已发生的提示。

1 个答案:

答案 0 :(得分：2)

根本原因是Structr尝试索引其toString（）方法返回null的对象。由于Lucene和Neo4j都没有过滤此类对象的过滤器，因此会导致数据库崩溃和不可恢复的数据库存储。

我们会尽快为Structr提供修复，我向Neo4j提出了一个问题：https://github.com/neo4j/neo4j/issues/6685
