我现在已经开始使用HAProxy了一段时间，但是仍然尝试着使用日志记录。该网站不时关闭，多数情况下访问速度非常快，它说：
无法访问此网站
意外关闭了连接。
，以及在ha-proxy日志中的许多类似内容：
haproxy[7938]: xx.xxx.xxx.xxx:36601 [06/Apr/2019:17:49:12.485] fe_https be_https/localdfw 6/0/5 0 SD 0/0/0/0/0 0/0
haproxy[7941]: xx.xxx.xxx.xxx:41143 [06/Apr/2019:17:49:12.490] fe_https be_https/localdfw 1/0/0 0 SD 0/0/0/0/0 0/0
我了解点点滴滴，例如SD表示“到服务器的连接在数据传输过程中由于错误而终止”和/0/0之前，这很可能意味着它来自客户端等，但是不太明白为什么会这样。谁能帮助我理解日志或给我一些指示，我应该在哪里看？不确定粘贴整个haproxy配置是否会有所帮助，但可以随时询问您可能希望查看的任何部分。预先感谢！
