看起来是把 http 请求发到了 1883 端口，被错误当作 MQTT 报文进行解析了。
log 里很多的 http 头

3

因为出现过发布消息收到客户机未连接的报错后，应用服务器这边断线重连的情况，而且当时mqtt服务器一直报消息队列满的错误，日志太多，初始错误无从查起，但是有大量上面的日志，所以还是需要分析清楚原因。
应用服务器发布消息使用的panho SDK，所以不会有http的请求，不知这个请求从何而来。

4

我看懂了，emqx开启了集群，这个日志是其中一台服务器上的，日志里面这个“2022-05-30T16:29:31.805780+08:00 [error] 172.24.21.184:38782 [MQTT] , Parse failed for function_clause”说明请求是从另一台服务器上发过来的。集群的服务器之间有这种交互吗？

5

应该不是这个意思。

报告 Parse failed 就是解析 MQTT 报文失败了，这个错误不会影响其他功能的。

通过日志看，存在大量的 HTTP 报文请求发送到 MQTT 的 1883 端口

GET /poweredby.png HTTP/1.0\r\nHost: emqx_cluster\r\nConnection: close\r\nUser-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.0.0 Safari/537.36\r\nAccept: image/avif,image/webp,image/apng,image/svg+xml,image/,/;q=0.8\r\nReferer: http://mqtt.rlinking.com/\r\nAccept-Encoding: gzip, deflate\r\nAccept-Language: zh-CN,zh;q=0.9\r\n\r\n

格式化下，即：

GET /poweredby.png HTTP/1.0
Host: emqx_cluster
Connection: close
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.0.0 Safari/537.36
Accept: image/avif,image/webp,image/apng,image/svg+xml,image/,/;q=0.8
Referer: http://mqtt.rlinking.com/
Accept-Encoding: gzip, deflate
Accept-Language: zh-CN,zh;q=0.9

你可以排查下是谁发的

Parse failed这个我理解，上面我摘取日志“2022-05-30T16:29:31.805780+08:00 [error] 172.24.21.184:38782 [MQTT]"是为了说明，172.24.21.184是我另一台服务器的地址，这两台服务器做了集群。所以这个1883的http请求是另一台发过来的。因为我我的应用服务器是通过panho的mqtt客户端sdk来连接emqx，不存在应用层面有通过http访问emqx服务器1883端口的行为，所以我觉得是否是因为集群的原因所以有这些错误请求？
