[Linux-cluster] openais question

Other way to observe the same (maybe other reason??):

After booting both nodes, when doing a service cman start on both nodes 
with some seconds of interval between both commands, the two nodes join 
the cluster and get quored.
When doing service cman stop on both nodes (also with some seconds of 
interval between both commands), one of the nodes successfully leaves 
the cluster, but the other prints this out

[root at m07 ~]# service cman stop
Stopping cluster:
   Stopping fencing... done
   Stopping cman... failed
Timed-out waiting for cluster
                                                           [FAILED]

while the messages in the log are
Dec  7 15:27:17 m07 openais[5436]: [TOTEM] The consensus timeout expired.
Dec  7 15:27:17 m07 openais[5436]: [TOTEM] entering GATHER state from 3.
Dec  7 15:27:32 m07 openais[5436]: [TOTEM] The consensus timeout expired.
Dec  7 15:27:32 m07 openais[5436]: [TOTEM] entering GATHER state from 3.
Dec  7 15:27:47 m07 openais[5436]: [TOTEM] The consensus timeout expired.
Dec  7 15:27:47 m07 openais[5436]: [TOTEM] entering GATHER state from 3.

Do you know what the problem is?
