[CentOS] problems with luci on CentOS 6.2

Hello,
I have a 5 node cluster.
virtsrv1n1
virtsrv2n2
virtsrv3n3
virtsrv4n4
virtsrv5n5

 From Luci I am unable to manage virtsrv3n3 machine. Luci is unable to 
reboot it for example and
if I select the node properties it shows me no status for Cluster 
Daemons for this specific node.
All the other nodes are fully manageable from luci.
from command line everything seems to work fine.

  virtsrv2n2.mydomain.org          2 Online, rgmanager
  virtsrv3n3.mydomain.org          3 Online, rgmanager
  virtsrv4n4.mydomain.org          4 Online, rgmanager
  virtsrv5n5.mydomain.org          5 Online, rgmanager

Looking the luci log i see this error if i try for exmaple to reboot the 
node from luci:

00:12:19,603 ERROR [luci.lib.ricci_helpers] Unable to retrieve the batch 
number from virtsrv3n3

ricci is working ok on the node as well as cman rgmanager and gfs2, and 
I do not have iptables active.
Any hints ?

thank you

Rick
