I am also worried about apisix-dashboard using constant CPU, even when not in use. We have setup apisix using docker. The apisix-dashboard -> manager-api, process is constantly consuming above 8% CPU !!!

[imtiaz-rahi]

@Linindoo can you please provide output (screenshot) of top / htop / btop for the manager-api of apisix-dashboard.

[Linindoo]

sorry,The process has already been restarted

@Linindoo can you please provide output (screenshot) of top / htop / btop for the manager-api of apisix-dashboard.

I also found that the use of memory was growing steadily, and I felt that there was a memory leak

[jinjianming]

@Linindoo您能否提供 apisix-dashboard 的 manager-api 的 top / htop / btop 的输出（屏幕截图）。

[imtiaz-rahi]

Definitely there are serious issues in the apisix-dashboard application.
Even when the dashboard portal not opened in browser by any user, it is consuming CPU constantly. Also, from @jinjianming report, we can use memory usage also increasing over time.

Will the devs please look into this.

try to apply this patch ? #2920

Is there a plan for this? When can I have a Docker image

[jinjianming]

I have deployed this repair patch, but it is not working well as the memory is still floating up

[hanqingwu]

I think maybe we should watch more time , because 20MB is so small sample

[jinjianming]

我想也许我们应该多看一些时间，因为20MB的样本太小了
