问题描述
问题：
数据库无法启动，以状态“ KILLED”退出，日志结尾为：Caused by: ... bind(..) Failed: Address already in use
与这些非常相似：
- Neo4j Desktop DB failed to start with with status 'KILLED'
- https://community.neo4j.com/t/database-failed-to-start/5612
- https://community.neo4j.com/t/database-failed-to-start-db-database-ee8e1c21-23d9-40fd-8a4e-02fd55a0d324-v4-1-0-exited-with-status-killed-check-the-logs/21045
日志结束于：
Caused by: io.netty.channel.unix.Errors$NativeIoException: bind(..) Failed: Address already in use

解决方法
这里已经有很多地址在使用中，因此很难解析，但是事实证明，调试日志中的这一点很重要：

好像桌面在该字段中遗漏了一些Java代码...
那之后数据库启动一切都很好。
