      Cluster: 7 nodes

      Node will be added:

      Build # 2.0.0-1945
      Environment: 8 nodes with 390GB SSD drive, 32GB RAM
      Bucket: 1 default bucket (1 replica), disable replica index.
      Number of clients: 1

      Load 40 million items to default bucket that push resident ratio down to around 62%
      Maintain load about 600 ops and 600 queries per second
      Create 1 design doc with 8 views. Let the initial index completed.
      Then add node 45 to cluster and rebalance.
      Rebalance was done at 01:35:40 - Friday Nov 9, 2012.

      Then at 07:19:06 - Fri Nov 9, 2012, control connection to memcached on node 42 was disconnected.
      Generate memcached backtrace on node 42, got error
