I have a Couchbase server cluster with 5 nodes with similar configuration. We found that network traffic from one of the node is 5 times than others node, but CPU is same (all around 40-50%), is it normal?
node1 traffic : 200M
node2 traffic : 200M
node3 traffic : 200M
node4 traffic : 1000M
node5 traffic : 200M
I tried remove node4, rebalance, then add node4 and rebalance again, but same situation, how to check and fix?
We are using Couchbase .NET client 2.7.x., Couchbase server is 4.5.1
