I am using openresty for our proxy services on amazon linux2. Upon high load, we started to see below errors in specific environment only
[crit] 10#10: *451875 connect() to 100.xx.xx.xxx:80 failed (99: Address not available)
And there are many 502 errors returned from the proxy layer itself. (there was no error/failure log found at the upstream).
I already have the ulimit increased and also based on other similar stackoverflow issues increased the local port range(ephemeral port). But still facing the issue. (This is running on k8s 1.20). Could anyone please help?
