    Description

      Steps to repro:

      * Had a four node cluster(replicas = 0)
      * Loaded 10 million items
      * While updating replicas observed rebalance exited with mover_crashed
      

      Rebalance exited with reason {mover_crashed,
      {unexpected_exit,
      {'EXIT',<0.17732.3>,
      {{{{{child_interrupted,
