环境

  • EMQX 版本：5.0.20
  • 操作系统版本：

重现此问题的步骤

升级到5.0.20版本，授权开启http请求之后，我们服务端还是请求量大还是会报错，帮忙看一下，错误日志如下：

可能和 HTTP 认证不一定有关系…看日志

msg: alarm_is_activated, mfa: emqx_alarm:do_actions/3, line: 416, message: <<“connection congested: #{buffer => 4096,clientid => <<“9c00b9c500e247199ed05eda96c6a3de”>>,conn_state => connected,connected_at => 1679323246848,high_msgq_watermark => 8192,high_watermark => 1048576,memory => 1023792,message_queue_len => 524,peername => <<“192.168.4.192:45922”>>,pid => <<“<0.30778.8>”>>,proto_name => <<“MQTT”>>,proto_ver => 5,recbuf => 374400,recv_cnt => 100,recv_oct => 90035,r”…>>,

是指你的 这个 MQTT 客户端，接收消息已经处理不过来了。所以才会被断开

3

这个哪个错误看出来的，有可以改的配置吗？我们客户端是服务端，需要对很多客户端进行转发请求，这个因为我们的发布和订阅权限没有分开，请求比较大

4

我们开启了授权就不行了，没开启就可以

5

您好, 你们多大的并发呢?

6

每秒几十条到上百条

7

发布和订阅建议分开，否则业务没法开启，特别是服务端这种业务

8

conn_congestion 这个告警看出来的

它指的就是你的客户端接受处理不过来了，很多消息堆积到了 TCP 上，EMQX 检查到了这种情况就会告警
