    Description

      To investigate further: When creating a 12x12 mesh between two clusters, XDCR memory usage seems to balloon up (7G in RSS) without actually any data transfer

      The test:

      1. Sets up 2 1-node clusters
      2. Create 12 buckets on each cluster, 100MB ramQuota
      3. For each bucket, create a replication to all target buckets, creating a mesh
      4. Replication has: 20000 statsInterval and 600 checkpointInterval
      5. The following internal settings are set:

      setInternalSettingsWithoutImport "C1" "TopologyChangeCheckInterval=60"
      setInternalSettingsWithoutImport "C2" "TopologyChangeCheckInterval=60"
      setInternalSettingsWithoutImport "C1" "RefreshRemoteClusterRefInterval=60"
      setInternalSettingsWithoutImport "C2" "RefreshRemoteClusterRefInterval=60"
      setInternalSettingsWithoutImport "C1" "ReplSpecCheckInterval=60"
      setInternalSettingsWithoutImport "C2" "ReplSpecCheckInterval=60"
