      Description

      15-node-cluster with HHD 8GB RAM and 4 core CPU. During initial loading, I have 1 k "sets" ops/ per sec for each node. Some of the nodes in cluster consume all the CPU resources
      Memcached (200%~250%), beam.smp (100%~150%). We only have compaction running, no views, rebalance. It's just a Key-Value load.

      I am using couchbase-python-client to do the multi-set loading.

      I attach the log from the node which suffers from this issue.
