Are there any other messages related to host "io" between the above?  It
seems strange just to have a lot of "topo" messages.

The above messages indicates that something outside the upstream LDM on
Flood broke the connection between Flood and Io.

What's the operating-system on Flood?  Is it up-to-date?
