502 ERROR "no live upstreams while connecting to upstream" with keepalive

[zhongcy]

I use keepalive with jdomain:

`
keepalive_timeout 65;
keepalive_requests 100;

upstream jdomain-upstream {jdomain test.my.com port=443 interval=60; keepalive 8;}`

but some time, requests get 502 "no live upstreams while connecting to upstream" error .

Hi @zhongcy , sorry I missed this one.

As with your the other ticket you opened, would you be able to provide a bit more information? As well as some more configuration and log output, would you be able to describe your observations a bit more? When you say "some time", do you mean that maybe one request every 60 seconds, a few requests a day sporadically? Or do you mean more like after some interval, suddenly all requests become 502 for some interval before recovering?

Thanks
