Hi Everyone. Recently we have been having issues with our deployments. Whenever we make changes to our existing services and build our deployments when the pods are created (say we have scaled 5/5 pods successfully without any errors or CrashLoopbacks) out of the 5 pods atleast one pod stops communicating with the other services. It’s connectivity looks good, no error logs but it doesn’t communicate with other services and does not push any messages to RabbitMQ as well.
We have been trying to know the root cause for this issue.
