> Following is proxy server show, {color:#de350b}too many connections from one
> client{color}, this caused the proxy server hang, and the yarn web can't jump
> to web proxy.

> Following is the AM which is abnormal, but proxy server don't know it is
> abnormal already, so the connections can't be closed, we should add time out
> support in proxy server to prevent this. And one abnormal AM may cause
> hundreds even thousands of connections, it is very heavy.
> !image-2021-03-29-14-05-32-708.png|width=669,height=101!
>
> After i kill the abnormal AM, the proxy server become healthy. This case
> happened many times in our production clusters, our clusters are huge, and
> the abnormal AM will be existed in a regular case.
>
> I will add timeout supported in web proxy server in this jira.
