[Sheepdog] Cluster appears down but nodes report different epochs

When I checked on the cluster this morning I see the following from
cluster info. A sheep and corosync process was found on all nodes
except blade162 which didn't have a sheep process but did have a
corosync one. I'm not sure what has happened. We have not had a
network interruption that we are aware of as all nodes are on the same
switch (along with countless other production systems). Logs from
each node can be found
http://www.stormpoint.com/files/sd_2011-11-07.zip. Total
un-compressed size is ~ 254MB and this download size is around 21MB.
When I left Friday, this is how our cluster looked:
All nodes were running version 0.2.4_63_gd56e3b6
