Description
1. Create 10B items
2. Delete 10B items
Observe that the mem_used it showing as 0B. I observed the cluster when ~8.5 billion items were deleted. Not sure since when mem_used is consuming 0B.
This seems to be a memory accounting issues. memory that should be freed from some other arena is getting freed from mem_used. I am not quite sure on this though. Attaching the logs for further debugging.
