    • Bug

    Description

      Setup:

      • 4 data nodes, 1 index node, 1 query node
      • 1 bucket (no replicas)

      Steps:

      • Load 20M items

      It's rather hard to believe that memcached uses exabytes of memory:

      # /opt/couchbase/bin/cbstats -b bucket-1 -p password 127.0.0.1:11210 all | grep mem_used
      		 
       mem_used:                                              18446744073706343008
