Cluter Configuration - How do you make it work?

Hi guys,

I am running a 2-headed cluster on Alfresco Community 3.3g on Ubuntu 10.04 using a shared content store (via NFS) and a shared database. I have followed all the instructions at

The problems I am having are numerous but, while simple content changes appear to replicate:
  1. Searches on both head nodes return different results (indexes not replicating?)
  2. Large deletions from the repository don't replicate (one node thinks the data is there, the other does not)
  3. Permissions do not replicate from one node to another (and an ACE here, it doesn't show up there)
  4. Customise the user dashboard in Share and it does not replicate to the other node

What exactly is it that I am doing wrong?

Here's the important properties from from one of the nodes:

# Cluster configuration

# Content and index locations

# Index configuration
index.tracking.cronExpression=0/5 * * * * ?

The /var/lib/tomcat6/shared/classes/alfresco/extension/ehcache-custom.xml is simply copied from the .sample file in the 3.3g distribution.

The time on the boxes is in sync, NTP is installed on both, they are spot on.

What is going on?
