@Lam_Tran by any chance do you run multiple temporal clusters in the same k8s cluster? If you do, you will need to use different port for ringpop membership communication. Otherwise, pods from 2 clusters would steal shard and task queues from each other causing lots of issues. The current solution is to use different port for different clusters.
