【问题描述】：
我正在使用 mongo 数据库链接到 Ubuntu 14.04 的亚马逊服务器上的 AngularJS/NodeJS 网站。
自 1 个月以来，每 5 或 6 天我的数据无法访问，我无法使用邮件/密码连接到网站。我需要关闭数据库并重新启动它以使其正常工作。并且所有存储的数据都丢失了。
我不明白为什么，日志文件看起来很正常。 这是出现错误时的完整日志

当我启动数据库时，我使用这个命令
sudo mongod --fork --logpath /var/log/mongod.log --dbpath /home/ubuntu/data/db
是因为我使用 sudo 来启动数据库吗？也许 mongo 需要一些读/写权限才能做一些事情，而他不能这样做，所以 bug 出现了？
我的第一个想法是因为服务器太小，所以我将它从 8Go 增加到 16Go，但这没有任何改变，并且昨天出现了错误
【问题讨论】：
-
"dropDatabase BACKUP_DB starting" 日志中的这一行是什么？
-
我不知道他做了备份。在下一行中，他启动了一个 dropDatabase moretheanwinebo 然后他删除了数据库。也许他永远不会重新注入其中的数据
