百度云部署的项目微服务项目，近一个月每天随机一个点gateway的cpu直接一百多，

正常的时候都不超过百分之10 忽然一下服务就断了 一看gateway的cpu直接超过100了 用的nacos 是这个优化的问题吗

是不是被ddos

有关系

惊群效应？还是突然请求增多 如果是突然请求增多 你被搞了 如果突然来一个请求 cpu很高 应该是惊群了

惊群那点消耗cpu都不带动的。应该就是内核没优化还有event扩展没装，单个进程连接数超1024内核一直刷日志 Too many open files 了。cpu 100%时 运行 strace -ttp 进程pid 就能看出问题

哦哦 这个必须优化内核 event扩展必须装

各位大佬 今天早上又出现了！
