We are using a 2 nodes cluster on Couchbase version 3.0.1 Community Edition.
The node is dropping out of cluster and we have to add it back manually sometimes to the cluster.
We see that one of the node’s CPU utilisation is going high at about 90+ %. And we noticed that the node turns yellow for a couple of seconds during this time.
The operations per second for the buckets go down drastically.
The logs show the below line:
Haven’t heard from a higher priority node or a master, so I’m taking over. (Attached the log screenshot for reference).
We have not configured any XDCR.
Support will be appreciated.
