1.压力测试，服务端当做设备端连接EMQTX，订阅了连接主题
2. 1秒1万条数据，服务端接收断开
出现异常：
2023-12-15T06:35:35.773310+00:00 [error] supervisor: ‘esockd_connection_sup - <0.2786.0>’, errorContext: connection_shutdown, reason: #{max => 1000,reason => message_queue_too_long,value => 5426}, offender: [{pid,<0.10555.3>},{name,connection},{mfargs,{emqx_connection,start_link,[#{enable_authn => true,limiter => undefined,listener => {tcp,default},zone => default}]}}]
我需要怎么处理这个问题，或者优化
优化/细分订阅端订阅的主题，使用共享订阅，或订阅更细粒度的主题。
看这条日志是因为这个客户端订阅的主题有过多的消息，短时间内大量的消息涌向同一个客户端会导致它的压力过大。
这个客户端是我的服务器，我做了扩展，所以在不考虑队列大小的情况我应该怎么优化，增加队列大小，或者说增加内存提升服务器性能？
设置为0和设置为100000都会打印异常，服务端还是断开了，实际设置没有效果,5.1.16版本
{“time”:1703147090879911,“pid”:“<0.2821.0>”,“msg”:“supervisor: ‘esockd_connection_sup - <0.2821.0>’, errorContext: connection_shutdown, reason: #{max => 1000,reason => message_queue_too_long,value => 2999}, offender: [{pid,<0.3303.0>},{name,connection},{mfargs,{emqx_connection,start_link,[#{enable_authn => true,limiter => undefined,listener => {tcp,default},zone => default}]}}]”,“level”:“error”,“error_logger”:{“type”:“supervisor_report”,“tag”:“error_report”},“domain”:[“supervisor_report”]}
客户端断开以后，重新连接会出现警告日志
