Gah, sorry, I keep fixing that and it keeps reappearing.

dlm inter-node communication is not working here for some reason.  There
must be something unusual with the way the network is configured on the
nodes, and/or a problem with the way the cluster code is applying the
network config to the dlm.

Ah, I just remembered what this sounds like; we see this kind of thing
when a network interface has multiple IP addresses, and/or routing is
configured strangely.  Others cc'ed could offer better details on exactly
what to look for.
