Problems for editing files in a clustered environment

[alfiasco]

I have followed the instructions for HA Config found here:

http://wiki.alfresco.com/wiki/High_Availability_Configuration_V1.4

I have placed the dir.root directory on a shared filesystem (with NFS)

I have 2 clusters.

When I add a node on the cluster1, this node is added on the node 2.
When I delete a node on the cluster1, this node is delete on the node 2.
So, it works fine when i add or delete some nodes. But when I edit a file on a cluster, this file on the second cluster is not modified.

Do I need to configure Hibernate to avoid this problem ?

I would like to know how to configure the "multicastGroupAddress" in ehcache-custom.xml. Do I need to create a group on my network ?
