V8 will not trigger a full mark-sweep & mark-compact until there is memory pressure for the max-old-space-size, which is 1.6GB on a 64bit system. This means that Kibana will, at times, consume over 1.6GB of RSS memory.
Bypassing this can be done by starting with `--dev` or explicitally setting `max-old-space-size`. For example: `NODE_OPTIONS="--max-old-space-size=1024" ./bin/kibana`
