Martin, Thank you for more information. I found a mis-configuration of riak's app.config. The backend of riak for Riak CS is riak_cs_kv_multi_backend (look out for _cs_). This is the custom riak_kv backend for Riak CS. The error of "s3cmd ls" was caused by this.
As for MB boundary stop, the issue https://github.com/basho/riak_cs/issues/613 may be related. Although not direct way to treat it, some points which may help: - As Seth said, upgrade to 1.4, which can reduce network communication between riak nodes - Set pb_backlog to 256 or higher in riak_api section of riak's app.config Regards, Shino _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
