java - Neo4j:2.2.3:服务器在 "Detected incorrectly shut down database, performing recovery"后无法启动

Question

neo4j 服务器意外关闭显然是由于 RAM 使用过多(我的 VPS 统计显示 > 32 GB 使用)。之后我尝试启动服务器。由于花费的时间太长，我使用 Ctrl+C 停止了该过程。我试过用控制台启动它。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."*
org.neo4j.kernel.lifecycle.LifecycleException: Component 'org.neo4j.kernel.Recovery@4dad40e0' failed to initialize. Please see attached cause exception.

我注意到错误是 Caused by: java.lang.Error: Maximum lock count exceeded. 我无法启动数据库。当我在控制台模式下启动时，只是说“检测到错误地关闭数据库，正在执行恢复..”并且同时在 messages.log 中出现上述错误。 如果在 graph.db 中可以进行一些手动清理，请提出建议。 非常感谢任何帮助。
