beam.smp ( erl_bestfit_alloc.c:435 ) segmentation fault when rebalancing a new node to a cluster with 2 buckets and 1 design doc per bucket

    Details

      Description

      Cluster information:

      • Load 9 million items to both buckets
      • Cluster has 2 buckets, default (3GB) and saslbucket (3GB)
      • Each bucket has one doc and 2 views for each doc (default d1 and saslbucket d11)
      • Create cluster with 10 nodes installed couchbase server 2.0.0-1708

      Doing rebalanc in, out, failover.
      Last failed was rebalance add 2 nodes, 23 and 24 into cluster.
      During rebalance, node 23 suddenly down. Rebalance failed as expected.
      Then later, memcached on node 13 was killed and restart.
