For various reasons, I have to run 1.6.0 of ES.

I've noticed in my memory graphs my ELK cluster (5 nodes) is using 1GB more per day on each node.

[cluster.name](http://cluster.name): elasticsearchlogstashkibana  
[node.name](http://node.name): "elksrv1"  
node.master: true  
node.data: true  
index.number\_of\_replicas: 2  
index.number\_of\_shards: 5  
network.host: 0.0.0.0  
cluster.routing.allocation.node\_concurrent\_recoveries: 2  
indices.recovery.max\_bytes\_per\_sec: 20mb  
indices.recovery.compress: false  
discovery.zen.minimum\_master\_nodes: 3  
discovery.zen.ping.multicast.enabled: false  
discovery.zen.ping.unicast.hosts: ["elksrv1","elksrv2","elksrv3","elksrv4","elksrv5"]  
script.engine.groovy.inline.update: on  
http.cors.allow-origin: "/.\*/"  
http.cors.enabled: true  
threadpool.search.queue\_size: 10000  
cluster.routing.allocation.disk.threshold\_enabled: false  
cluster.routing.allocation.enable: all

I have thought of adding:

bootstrap.mlockall: true  
gateway.recover\_after\_nodes: 5  
gateway.recover\_after\_time: 5m  
gateway.expected\_nodes: 5

but haven't.

Any thoughts from anyone on Elasticsearch/ELK clusters memory increasing like this?

Does your cluster store lot of new datas every day or not ?

Only about 1.2GB to 1.3GB per day.
