I have detailed replication scenario here. Load Data using Dgraph w/ Kubernetes - #9 by Ann_Zhang
This happens when I was using live loader to load data into Dgraph.
I have uninstalled Dgraph cluster and cleaned all the data bound to all the pods, and re-installed Dgraph cluster on my EKS, but still that the tcp error happened in a infinite loop. However, using curl command to apply schema, then use graphql query to mutate data (insert or update) has no problem. So the problem focus on Live Loader import data.
