People are certainly interested. You’re running on the bleeding edge of technology, you’re very brave ;).
I’m not quite sure how to interpret “memory utilization stays around 18%”. 18% of total physical RAM or heap? I’m assuming the former.. I’m curious, how did CMS and G1GC fail? It’s perfectly understandable if the failures were due to stop-the-world GC pauses; they can lead to timeouts which can cause replicas to be put into recovery, or Zookeeper to think the node died etc… In extreme cases this means that the entire cluster goes down.
