Hi, Your node has less than 1GB of heap memory (see the line below). Please allocate proper amount of heap to the server nodes, as Alexey suggested.
^-- Heap [used=528MB, free=42.03%, comm=911MB] In addition, if you're going to have more than 10 GB of data per node, I would recommend to use offheap memory [1]. Otherwise you will likely have long GC pauses.
