Hi there, Can someone please point me in the right direction to understand what could be possible reasons of high heap usage by inactive/idle master node. This node doesn't participate in indexing or querying data and dedicated to master node config so i couldn't understand as to why this node is consuming high heap mem (71.5% max). Generally it goes upto 72% and comes down to 12% and again in few days shows rapid mem growth. our elk set up is as follows - 1. 3 dedicated master nodes - - ``` out of which only 1 inactive master consumes high heap mem (>70%) ``` - ``` other idle master consumes between 6-7% heap mem ``` - ``` Finally active master consumes ~40% heap mem ``` 1. Master node heap mem size - 15 GB (50% of total mem) 2. elastic version - 6.4.2 3. 5 data nodes - heap mem is usually between 50-60% which is OK Thanks in advance ---
