无法启动Neo4j服务器

由于系统意外关闭，neo4j服务器关闭，现在我无法重新启动服务器。如何在不丢失数据的情况下重新启动它。（我无法承受丢失数据的代价）

这是错误日志

ERROR o.n.s.advanced.AdvancedBootstrapper - Failed to start Neo Server on port [7474]

最初的海报声称这个问题是通过减少Java堆大小和内存配置来解决的

将

wrapper.java.initmemory

配置为不超过可用系统内存的MB值。

能否提供有关数据存储文件的更多详细信息？您是否尝试过更改配置以允许商店级升级？（确保首先备份存储文件）减少wrapper.java.initmemory解决了问题。看起来其他进程正在消耗ram。谢谢。很高兴你能弄明白。
