Indexing 11 ddocs might push system into swap pretty quickly

    Details

      Description

      1 bucket.
      6 GB bucket, 8 gb system ram,
      10M items
      40% active and resident ratio.

      It seems like that indexing 11 ddocs with 2 views each, seems to push the system into swap, pretty fast.
      Seeing this on 2.0 large cluster, with similar setup as well.
      What are the bounds for 2.0 when someone wants to use indexes and upto how many?

      See the screenshot attached for what we are seeing, in the functional tests.
