RAM memory for Cesium+

I installed a new test node Cesium+, with docker.

But, I see memory usage in more than 5 GB.

Is this normal?


ElasticSearch has been written in Java.
The JVM memory is reserved when startup, and should changes at lot when running. Two env variables can be set, before launching : for min and for max memory usage.
I dont know the ES default value, but you can check in shell script files (under cesium-pm lus-pod/bin folder)
