When you want your cluster to repair failures _fast_, the components
have to sync their state _fast_. So they have to talk a lot, not in
terms of megabytes but in terms of small packages with low latency in
submission.

So, yes that traffic is normal. Why is there a firewall between your
nodes on the network where the cluster traffic happens?

Have fun,

Arnold
