      Description

      Environment:
      8 windows server 2008 R2 64 bit in ec2. Each server has 7.5 GB RAM and 45GB EBS disk to store data.
      Create a 6 nodes windows cluster in ec2
      Create default bucket with one replica and index enable. Erlang set to +S 16:16

      10.96.107.176
      10.110.222.56
      10.214.194.95
      10.111.66.215
      10.2.63.249
      10.110.206.19

      Loading phase:

      • Create one default bucket and load 24 million items to this bucket.. Each item has size from 128 to 512 bytes.
      • Right after start loading items to cluster, create a doc with 2 views
        curl -v -X PUT -H 'Content-Type: application/json' 'http://ip:8092/default/_design/d1' -d '{"views": { "v1":
        Unknown macro: {"map"}

        , "v2":

        Unknown macro: {"map"}

        }}'

      • Wait until indexing reach more than 80%, do query 2 views with command

      curl -X GET 'http://IP:8092/default/_design/d1/_view/v1?stale=ok&limit=500'
      curl -X GET 'http://IP:8092/default/_design/d1/_view/v2?stale=ok&limit=500'

      Then I saw a node in cluster unstable, then down due to control memcached timeout.
      At the time one node down, I tried to got information using cbstats but the node did not response.
      Then the node came up in UI with N/A in RAM Usage.
      Then other node in cluster, one by one became up and down and got the correct value for disk and memory. 4 of 6 nodes shows negative number in both memory and disk storage.
      In cluster overview, it shows only total of 2 nodes out of 6 nodes (90 GB instead of 270 GB)
