    Description

      Build 6.0.0-1693

      Observed that in one of the runs of high bucket density test with 30 buckets, swap rebalance of one eventing node failed.
      In a test, we have only one function deployed which is doing bucket-op as below.
      In swap rebalance we take only eventing node in cluster out and push another eventing node in.
      Note that it is not consistently reproducible and failed only once in around 6 attempts.

      Function deploy data:

      "actionsVisible": true,
      "appcode": "function OnUpdate(doc, meta) {\n    bucket1[meta.id]=doc[\"alt_email\"];\n}\n\nfunction OnDelete(doc) {\n}\n",
