Having an issue during high traffic will get errors in the log with 502, and
get these errors--"no live upstreams while connecting to upstream"
In my configs it is set to 5 max fails, default of 10s fail time.
1. Does it try the same session within those 10s--every 2 seconds? If I
made it 20 seconds would it try every 4 seconds?
2. If another session fails, is it cumulative in that 10s or is it for each
3. If the server is marked unavailable; what about the current sessions?
4. What would be a better solution? Extending the fail time? Lessening the
fail time and less attempts?
