Mongodb 系统中打开的文件太多
Mongodb too many open files in system
我们的软件包含：
centos、nginx、kestrel http 服务器、dotnet 核心 (v2.0.8) 应用程序可与 mongodb (v3.6.7)
配合使用
kestrel http 服务器有时会停止响应，似乎来自 mongodb 驱动程序连接的错误如下所示记录在第 3 行
是什么导致了这个问题？
我已将此主题的最大打开文件选项配置为 640000
但是没有解决，请大家帮忙解决这个问题，谢谢大家。

如果您使用的是 CentOS 6 或更高版本，那么您可能需要遵循
下面的说明。
Red Hat Enterprise Linux and CentOS 6 place a max process limitation
of 1024 which overrides ulimit settings. Create a file named
/etc/security/limits.d/99-mongodb-nproc.conf with new soft nproc and
hard nproc values to increase the process limit. See
/etc/security/limits.d/90-nproc.conf file as an example
