      Description

       

      Build: 6.6.0-7861

      Scenario:

      • 4 node cluster, Couchbase bucket (replicas=2)
      • Start two transactions in parallel (One will succeed and other will rollback)
      • Rebalance out 1 node from the cluster
      • +----------------+----------------------+--------------+
        | Nodes          | Services             | Status       |
        +----------------+----------------------+--------------+
        | 172.23.105.205 | kv                   | Cluster node |
        | 172.23.105.155 | fts, index, kv, n1ql | Cluster node |
        | 172.23.105.206 | [u'kv']              | --- OUT ---> |
        | 172.23.105.159 | kv                   | Cluster node |
        +----------------+----------------------+--------------+
        

      Observation:

      During rebalance-out, rebalance operation fails with reason "mover crash - child interrupted-socket closed" message

      Failure logs:
