Yeah, if snapshot can’t be done for long it will make the server go out of memory very quickly. Are you using the Go client to load the data? ---

yes. and the dgraph image is dgraph/dgraph:v1.0.4 ---

Ok, we’d need to replicate this and see why snapshot isn’t happening. What is your general setup like and how do you load this data? ---

the cluster consists of 5 dgraph zeros and 30 servers ```auto dgraph zero --replicas 3 --my=$(hostname -f):5080 --peer dgraph-zero-0.dgraph-zero.default.svc.cluster.local:5080 --idx $idx --rebalance_interval 60m0s ``` ```auto dgraph server --my=$(hostname -f):7090 \ --memory_mb 6000 \ --zero dgraph-zero-0.dgraph-zero.default.svc.cluster.local:5080 \ --idx $idx \ --port_offset $offset \ --debugmode \ --query_edge_limit 18446744073709551615 ``` we load the data via Go client with transaction batch size set to 100,000. ---

I fixed a small issue yesterday. So maybe try with `dgraph-io/dgraph:master` and see if it still happens. I will spin up a Kubernetes cluster soon and try to load data using `dgraph live` to see if I can replicate this issue. ---

The warning can be there temporarily. We will change the logs to mention it as a warning which is logged only in debug mode. It is only an issue if it remains for a long time. ---
