我们的软件包括:
centos、nginx、kestrel http服务器、dotnet core(v2.0.8)应用程序与mongodb(v3.6.7)合作
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记录在第三行
是什么导致了这个问题?
我已经用这个主题将max open files选项配置为640000
https://medium.com/@mshanak/soved-dotnet-core-too-many-open-files-in-system-when-using-postgress-with-entity-framework-c6e30eeff6d1
但是没有解决的请帮我解决这个问题谢谢大家。
