Description of problem:
Every one is in the cman cluster:

[root@morph-02 root]# cat /proc/cluster/nodes
Node  Votes Exp Sts  Name
   1    1    5   M   morph-01
   2    1    5   M   morph-03
   3    1    5   M   morph-05
   4    1    5   M   morph-04
   5    1    5   M   morph-02

[root@morph-02 root]# cat /proc/cluster/status
Protocol version: 5.0.1
Config version: 1
Cluster name: morph-cluster
Cluster ID: 41652
Membership state: Cluster-Member
Nodes: 5
Expected_votes: 5
Total_votes: 5
Quorum: 3
Active subsystems: 0
Node addresses: 192.168.44.62

I then do a 'cman_tool leave' on all nodes at the same time and the
cmd on the "last" node hangs.

All nodes but morph-02 are no longer in the cluster:
root@morph-01 root]# cat /proc/cluster/status
Protocol version: 5.0.1
Config version: 1
Cluster name: morph-cluster
Cluster ID: 41652
Membership state: Not-in-Cluster
[root@morph-01 root]# cat /proc/cluster/nodes
Node  Votes Exp Sts  Name


[root@morph-03 root]# cat /proc/cluster/status
Protocol version: 5.0.1
Config version: 1
Cluster name: morph-cluster
Cluster ID: 41652
Membership state: Not-in-Cluster
[root@morph-03 root]# cat /proc/cluster/nodes
Node  Votes Exp Sts  Name


[root@morph-04 root]# cat /proc/cluster/status
Protocol version: 5.0.1
Config version: 1
Cluster name: morph-cluster
Cluster ID: 41652
Membership state: Not-in-Cluster
[root@morph-04 root]# cat /proc/cluster/nodes
Node  Votes Exp Sts  Name


[root@morph-05 root]# cat /proc/cluster/status
Protocol version: 5.0.1
Config version: 1
Cluster name: morph-cluster
Cluster ID: 41652
Membership state: Not-in-Cluster
[root@morph-05 root]# cat /proc/cluster/nodes
Node  Votes Exp Sts  Name


But morph-02 has a different view:

[root@morph-02 root]# cat /proc/cluster/status
Protocol version: 5.0.1
Config version: 1
Cluster name: morph-cluster
Cluster ID: 41652
Membership state: Transition-Master
Nodes: 4
Expected_votes: 5
Total_votes: 4
Quorum: 3
Active subsystems: 0
Node addresses: 192.168.44.62

[root@morph-02 root]# cat /proc/cluster/nodes
Node  Votes Exp Sts  Name
   1    1    5   X   morph-01
   2    1    5   M   morph-03
   3    1    5   M   morph-05
   4    1    5   M   morph-04
   5    1    5   M   morph-02

...and a still hung cman_tool leave cmd.

All the other nodes spit out the following messages:
Jan 26 17:24:38 morph-01 ccsd[3813]: Unable to connect to cluster
infrastructure after 990 seconds.
