Hello, Our Production Elasticsearch Cluster nodes are constantly getting a Java out of memory. Another strange phenomenon is that we have 2 nodes which their JVM is extremely high between 90%-99% , after a cluster restart they have still high JVM Memory. The Production Cluster has : 3 Master Nodes, type: m3.large 3 Nodata Nodes, type: m3.xlarge 23 Data Nodes, type: c3.2xlarge. More details: Nodes: 29 Indices: 16 Shards: 740 Data: 12.11 TB CPU: 452%Memory: 145.13 GB / 240.74 GB Version: 1.4.2 Here is the logs from the nodes: [2015-02-03 01:28:01,237][WARN][index.warmer]
