Hello,
I have a four node cluster running with K8 in Minikube locally, with sharding. Everything is functioning as normal. I use K8 API with AKAK Management for cluster formation and discovery. However, I see a lot of output stream error with pool shut down message in the log as shown below. Is there anything I need to specifically look for.
