Uneven Resident Ratio on each Data node

Hi,

I have a 14 node cluster hosting data service only. The resident ratio (RR) shows 88.7% for one of the buckets. On going to statistics for this bucket, it shows 96% RR for the last minute. The RR is all over the place for each node from a low to 60% to high of 100% for the 14 nodes.

Questions

  1. Why the discepency in the main page of buckets (88.7%) and the statistics page (96%) for RR ?

  2. Why the RR is divergent for each node by such a big margin ?

Thanks
Ganesh
