版本: V2Ray v2.5.2 (One for all) 20161109
服务器: Ubuntu 16.10 x64
客户端: macOS 10.12.1 (16B2555)
访问方式: Chrome, SwitchyOmega, socks/vmess/kcp
现象: 间歇性访问不了墙外网站

例如在访问 vultr.com 时, 突然打开新页面时就卡住了, 此时再访问google.com/twitter.com等网站时也都卡住. 重启 c/s 的 v2ray 后还是这样, 但等十几分钟后会恢复正常.

客户端日志有大量的Failed to read response header: EOF 错误.
服务器日志看不到错误信息.

只grep了vultr的日志, 这是客户端的

同一台服务器, 改用ss(v2ray) -> kcptun -> ss(v2ray)之后, 没再出现过这种情况.

猜测是大量的并发连接导致 UDP NAT 出了什么问题，2.8 中减少了 UPD 端口的用量，对这个问题有一定的帮助。
