Hmmm also noticed that dgraph_server_2 and dgraph_server_3 are throwing errors similar to this:
dgraph_server_2.1.u4kina8qwx3s@AP-GRAPH-2 | 2018/04/16 16:16:24 pool.go:158: Echo error from zero:5080. Err: rpc error: code = Unavailable desc = all SubConns are in TransientFailure
dgraph_server_2.1.u4kina8qwx3s@AP-GRAPH-2 | 2018/04/16 16:16:27 groups.go:105: Error while connecting with group zero: rpc error: code = Unavailable desc = all SubConns are in TransientFailure
I don’t think the latest branch was doing this. Are we missing a detail in the configuration you supplied me with?
