grpc 客户端报错： connection reset by peer

在k8s 上部署golang 的 grcp 服务端, 客户端是 php grpc 扩展 问题 : 客户端 connction reset by peer 的情况 , 利用了tcp本身的keepalive 包来保活，也修改了 net.ipv4.tcp_keepalive_time 等参数，但是还会频繁出现断连的问题， ```go func main() { grpcServer := grpc.NewServer( grpc.KeepaliveParams(keepalive.ServerParameters{Time: 600 * time.Second}), grpc.MaxConcurrentStreams(10000), ) protoc.RegisterTServiceServer(grpcServer, new(handle.TImpl)) reflection.Register(grpcServer) addr := startcfg.GetLisAddr() lis, err := net.Listen("tcp4", addr) if err != nil { panic(err) } grpcServer.Serve(lis) } ``` pod中内核参数 ```shell sysctl -a|grep tcp_keepalive net.ipv4.tcp_keepalive_intvl = 30 net.ipv4.tcp_keepalive_probes = 10 net.ipv4.tcp_keepalive_time = 600 sysctl: reading key "net.ipv6.conf.all.stable_secret" sysctl: reading key "net.ipv6.conf.default.stable_secret" sysctl: reading key "net.ipv6.conf.eth0.stable_secret" sysctl: reading key "net.ipv6.conf.lo.stable_secret" ``` 机器上的 值也改了，求大佬给出一些思路
