    Description

      Rebalance after failover, 3 -> 4 nodes, 1 bucket x 100M x 2KB, DGM, 1 x 1 views, 10K ops/sec, 400 qps

      Steps:
      1. "Failover" one node.
      2. Add it back.
      3. Wait for predefined time (20 minutes).
      4. Trigger cluster rebalance, wait for rebalance to finish.

      Memcached crashed on newly added node (172.23.96.18).
      Core dump and extracted binary is still there:
