    Description

      We observe rapid growth of swap usage on one of nodes during initial indexing (node 10-2-1-63):

      free -m
      total used free shared buffers cached
      Mem: 32098 22717 9380 0 99 657
      -/+ buffers/cache: 21960 10137
      Swap: 10095 6903 3191

      PID=24261 - Swap used: 412 - (beam.smp )
      PID=24419 - Swap used: 5459804 - (memcached )

      diag info attached but not very helpful. I'm going to start test with running atop.
