Nginx throws connection refused error intermittently. Here is the error stack trace,
[error] 12035#12035: *177490 connect() failed (111: Connection refused) while connecting to upstream, client: xxx.xx.xx, server: xxx.xx.xx, request: "POST / HTTP/1.1", upstream: "xxxx", host: "xxx.xx.xxx"
These errors won't occur all the time, but they appear in the log file intermittently. I think it's a serious issue since these errors occure very often. Can someone please shed some light on this issue?
Thanks
