It is really rather odd. Node 1 can obviously see the joinreq messages - at
least tcpdump can, but cman is either not seeing them or ignoring them.

What really bothers me is that this seems to be affecting U2 and U4 - if both of
you were using U3 I would think no more of it :)

Annoyingly it's hard to debug at this level (you can't strace a kernel thread!).
I"m pretty sure that a reboot of node1 would fix the problem but that's hardly
helpful.
