      [<<"default">>,
      {config,
      {30,undefined},
      {30,undefined},
      undefined,false,false,
      {daemon_config,30,131072,20971520}},
      false,
      {[{type,bucket}]}]}}]) terminated unexpectedly: {{bad_return_value,
      {stop,
      {error,
      {bucket_create_error,
      {memcached_error,
      key_eexists,
      undefined}}}}},
      {gen_server,
      call,
      [{'ns_memcached-default',
      'ns_1@cb-example-0000.cb-example.default.svc'},
