    Description

      We might have allocations in internal memory structures (other than HashTables) that can be released before we touch the Active HashTables
      One of those structures is Checkpoint. In this particular case we have ~ 10GB in checkpoints that we could release before triggering Eviction from HTs
      In general the outbounds DCP readyQs allocations might spike as well in 7.1.x datanodes. We might want to consider to release memory from there as well, but that would mean forcing DCP disconnections. I mention that just for reference for now, I wouldn't touch that before Checkpoints.
