我使用mongo数据库链接到使用ubuntu 14.04的Amazon服务器上的AngularJS / NodeJS网站。
从1个月开始，每隔5或6天我的数据无法访问，我无法通过邮件/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。并且存储的所有数据都将丢失。
我不明白为什么，日志文件看起来很正常。 这是错误出现时的完整日志

当我启动数据库时，我使用此命令
sudo mongod --fork --logpath /var/log/mongod.log --dbpath /home/ubuntu/data/db
是不是因为我使用sudo启动数据库？也许mongo需要一些读/写权限才能做某些事情，他不能出现错误？
我的第一个想法是因为服务器太小所以我把它从8Go增加到16Go但这没什么变化，昨天出现了这个bug
