This means that the cluster manager, cman, has shut down.  When that
happens it forcibily takes down all the dlm lockspaces which results in
the assertion failures below if gfs happens to be running.

There may be more information in /var/log/messages about why cman shut
down, but it's probably because of the network failure.
