Sorry for the extremely delayed reply.

This message is part of the code designed to make sure that
blocks are stored on the correct hosts.  We have reworked
that code significantly recently but it is still an area of
active development.  It probably had bugs then and still has
bugs in more recent snapshots.

If you run lsd with the '-r' flag, it should suppress these
messages and work fine in stable test environments where nodes
are not joining and leaving the system.

CFS itself may be more stable in older snapshots.
