neo4j服务器的意外关闭显然是由于过多的RAM使用(我的VPS统计数据显示> 32 GB使用).接下来,我尝试启动服务器.由于耗时太长,我使用Ctrl C停止了该过程.我尝试使用控制台启动它.我在messages.log中收到以下错误

*"org.neo4j.kernel.lifecycle.LifecycleException: Component 'org.neo4j.kernel.Recovery@4dad40e0' failed to initialize. Please see attached cause exception."*

我注意到该错误是由以下原因引起的：java.lang.Error：超出了最大锁定数.我无法启动数据库.当我以控制台模式启动时,只是说“检测到错误地关闭数据库,执行恢复..”,并同时出现messages.log中的错误.
如果可以在graph.db中进行一些手动清理,请提出建议.
任何帮助是极大的赞赏.

解决方法:

此问题已修复,将包含在2.2.4版本中.有关更多详细信息,请参见https://github.com/neo4j/neo4j/commit/c9596af0d990d7dde9a9053799b7295985ae3c05.
