I’m using Couchbase Server 4.1 CE.
I have a 3 machine cluster with 32Gb of ram per machine.
I have 4 buckets with 4M, 3M, 10M, 6M documents.
I have 4 indexes one for each bucket.
I have setup 18Gb ram for Data and 10GB for indexes per node.
On dashboard i see this for each machine (give or take a few MB):
It says that is only using 8Gb and then 20GB is being used for other data.
The server is only running couchbase server, so can couchbase be using the 20Gb of ram to do other processing?
My N1QL queries are running slow when this state is reached and i have do restart the machines.
How can i find out whats happening here.
