Client memory usage continuously increases when using SSL connection

[nuomi666]

Using emqtt-bench to simulate 100,000 client connections and continuously send heartbeats. After all 100,000 clients have successfully connected and been maintained for a period of time, the client's memory usage continuously increases. Could this be a memory leak in emqtt-bench?

麻烦提供一下运行参数。

mqtt_bench conn -h 10.10.0.1 -p 28019 -u test -P 123 --ssl -V 3 -k 59 --prefix 'sub-' --shortids true -n 0 -R 1000 -c 100000

you could try -l with low mem mode.

If the proceses are just doing keep alive, it is unlikely the mem get GCed and you will see it grows until reach some GC point.

maybe the issue has been fixed in 0.4.29: #276
please give it a try @nuomi666

我在测试多并发的时候也发现了这个问题 :( emqtt_bench工具使用的内存会逐渐上升,导致我在测试长连接功能时,压测机的内存溢出导致系统崩溃.
我使用的版本是0.4.29
系统是 Ubuntu 22.04
运行命令: emqtt_bench conn -h 192.168.5.249 -c 50000 - i 10 --ifaddr 192.168.5.74
即使我使用了 -l 低内存模式 他也会逐渐上升.我只能寻找其他的工具来测试我的broker.
