Question

我已经在我的nginx日志中得到这些错误了很长一段时间了。我最近没有看到网站性能的任何问题，但是当我们有超过1000个用户连接时，我们遇到了问题。

以下是一些错误日志

2018/03/23 20:14:18 [错误] 1356＃0：* 540195 recv（）失败（104：   在代理升级连接时，对等方重置连接，客户端：   10.253.220.93，server：playtest2.ea.com，request：＆＃34; GET /socket.io/?email=email&name=name&clientId=35e9c1be-f1fc-4e34-ba68-ce72c6e905c8&version=2.0.0.1704 ＆amp; fullName = test＆amp; EIO = 3＆amp; transport = websocket＆amp; t = 636573072574620756-17 HTTP / 1.1＆＃34;，上游：   ＆＃34; http://127.0.0.1:3000/socket.io/?email=email&name=DICELA-RSTAR&clientId=35e9c1be-f1fc-4e34-ba68-ce72c6e905c8&version=2.0.0.1704&fullName=Dtest&EIO=3&transport=websocket&t=636573072574620756-17＆＃34 ;,   主持人：＆＃34; playtest2.xx.com＆＃34;

这是我的nginx conf，任何帮助将不胜感激。
