Upstream Response Time - High Value

[iliesh]

I installed the following module on one of our Proxy and noticed something strange related to the response time with one of the upstream server. For some reason, the response time is showing for about 9-10min, which is huge - by testing with curl I'm getting a few ms, so I just wonder why the VTS module will show such high value?

Nginx v1.16.0
VTS: 0.1.18

Please try again with the latest version.(3c6cf41)
I have merged #145 a few days ago.
Of course, this patch may not be the same problem as above.

@vozlt , thanks I was trying with the latest version - but the problem still persists. The problematic backend is actually a WSS endpoint, where nginx is proxying the traffic, if that will help you to identify the issue.

Hi, thank you for your comment.
We've continued to invest this issue for a long time. Nevertheless we cannot have any clues of the solution of this issue because we have not completely earn the reproducibility way to be occurred this. Could you tell us how to reproduce this issue more detail?

it's not a problem when your backend is a WSS wndpoint and upstream resonse time is pretty much high, because the connections from client to nginx and to upstream is not closed.
