Couchbase Cluster components :
- couchbase enterprise version 4.6.3
- 6 node(query, index, data)
- 2 nodes(index)
- 6 bucket
- The number of buckets with the most items is 60 million.
I have a one question about cpu utilization of nodes.
suddenly, one node of couchbase cpu utilization is 100%. role of this node is query & index and data.
also, indexer nodes are cpu utilization 100%.
in addition, couchbase cluster is not receive client connection and application server not connect couchbase cluster.
So, why is couchbase cluster 100% CPU? I usually keep only 20%, but suddenly couchbase cpu went up. It is already the third. Why is not the JAVA SDK load balancing to couchbase?
