V2ray-core: 经常 accept4: too many open files

Created on 9 Dec 2017  ·  6Comments  ·  Source: v2ray/v2ray-core

1) 你正在使用哪个版本的 V2Ray？（如果服务器和客户端使用了不同版本，请注明）
V2Ray v2.51 (One for all) 20171123

2) 你的使用场景是什么？比如使用 Chrome 通过 Socks/VMess 代理观看 YouTube 视频。
路由器使用ss-redir转到 v2ray开的ss端口

3) 你看到的不正常的现象是什么？（请描述具体现象，比如访问超时，TLS 证书错误等）
2017/12/09 23:43:00 [Warning]Transport|Internet|TCP: failed to accepted raw connections > Retry: [accept tcp 0.0.0.0:5600: accept4: too many open files] > Retry: all retry attempts failed

4) 你期待看到的正确表现是怎样的？
不要一直报错，看起来好像是连接不够用了，但是不知道原因。

5) 请附上你的配置（提交 Issue 前请隐藏服务器端IP地址）。

服务器端配置:
