       Failed 4 times in the last 30 runs. Flakiness: 27%, Stability: 86%
      Error Message
      Expected heap usage close to 49.930MiB, got 41.542MiB.

      Stacktrace

      UPDATE: It was discovered that unit tests were running with memtable_allocation_type: offheap_objects when we ship C* with heap_buffers.
      So we changed that in CASSANDRA-19326, now we test with memtable_allocation_type: heap_buffers. As a result, this test now fails all the time on 4.0 and 4.1.
