I delopy one nginx by docker which network mode is host,then I deploy fifteen tensorflow serving,the nginx upstream to them
I make reques,the qps is 1000,but the ack has too many error,if I don't use nginx,make request director to serving hte error is 0. the request error is:
grpcerror err:Error 14 unavailable tcp write failed 

the config is:

daemon off;
worker_processes 56;

pid /run/nginx.pid;

worker_rlimit_nofile 1024;

worker_shutdown_timeout 10s ;

events {
multi_accept        on;
worker_connections  16384;
use                 epoll;
}
