      Steps to Reproduce

      1. Create a 3 node cluster

      +----------------+----------------------------+--------------+
      		 
      | Nodes          | Services                   | Status       |
      		 
      +----------------+----------------------------+--------------+
      		 
      | 172.23.104.222 | [u'index', u'kv', u'n1ql'] | Cluster node |
      		 
      | 172.23.104.223 | None                       | <--- IN ---  |
      		 
      | 172.23.104.224 | None                       | <--- IN ---  |
      		 
      +----------------+----------------------------+--------------+

      2. Add a default bucket with replicas=0
      3. Load 50k items to the bucket with durability=MAJORITY
      Bucket statistics:

      +---------+---------+----------+-----+-------+------------+-----------+-----------+
      		 
      | Bucket  | Type    | Replicas | TTL | Items | RAM Quota  | RAM Used  | Disk Used |
      		 
      +---------+---------+----------+-----+-------+------------+-----------+-----------+
      		 
      | default | membase | 0        | 0   | 50000 | 5942280192 | 120322520 | 47570597  |
      		 
      +---------+---------+----------+-----+-------+------------+-----------+-----------+

      4. Rebalance out 1 node and start data loading(update, create, delete items) in a separate thread

      +----------------+----------------------------+--------------+
      		 
      | Nodes          | Services                   | Status       |
      		 
      +----------------+----------------------------+--------------+
      		 
      | 172.23.104.224 | [u'kv']                    | --- OUT ---> |
      		 
      | 172.23.104.222 | [u'index', u'kv', u'n1ql'] | Cluster node |
      		 
      | 172.23.104.223 | [u'kv']                    | Cluster node |
      		 
      +----------------+----------------------------+--------------+

      Rebalance failed: memcached crashed on ns_1@172.23.104.222
