I can see following lines in spring microservice logs every now and then and mostly whenever I hit my FTS query where 188.8.131.52 is my search node:
2018-01-31 10:42:04.791 INFO 18684 — [ cb-io-1-2] com.couchbase.client.core.node.Node : Disconnected from Node 184.108.40.206/ec2-54-218-6-25.us-west-2.compute.amazonaws.com
2018-01-31 10:42:04.860 INFO 18684 — [ cb-io-1-4] com.couchbase.client.core.node.Node : Connected to Node 220.127.116.11/ec2-54-218-6-25.us-west-2.compute.amazonaws.com
I have four node cluster and whenever I remove search node from cluster cluster loooks to be stable as rebalance button gone disable while when I add it it keeps enable and keepds enable even after clicking on it. From command line re -balance shows 100% completed every time. Kindly suggest me some steps to trouble shoot this issue please. Please let me know for further information.
