    Description

      Steps to reproduce:

      1. Create a 6 node cluster 3KV-2index-1query.
      2. Create about 10 buckets with 16 indexes in total.
      3. Load the docs until all of the buckets have data greater than memory.
      4. Kill memcached (either by OOM kill or by kill -9) and check that 1 KV node auto fails over.
      5. Do a delta recovery and rebalance.
