So it turns out that we were using a 5.5.12 and a 5.5.9 installation.  Once 
I changed the 5.5.9 to 5.5.12, it worked fine.

Subject: OutOfMemoryError when starting cluster in 5.5.12


Hi,

I'm trying to run a cluster with two machines (A and B), both Windows XP. 
The cluster was working fine in Tomcat 5.5.9 but I decided to upgrade to 
5.5.12 because of some improvements in memory management.  After the 
upgrade, the cluster stopped working.

Machine A starts up fine and looks for any active members, doesn't find any 
as expected and loads applications.  Machine B starts up with the following 
output:

INFO: Starting Servlet Engine: Apache Tomcat/5.5.12
Nov 1, 2005 11:20:36 AM org.apache.catalina.core.StandardHost start

Nov 1, 2005 11:20:38 AM org.apache.catalina.cluster.deploy.FarmWarDeployer 
start
INFO: Cluster FarmWarDeployer started.


The problem child being:

Exception in thread "Cluster-MembershipReceiver" java.lang.OutOfMemoryError: 
Java heap space

Any ideas what this might be.  Keep in mind that this was working flawlessly 
in 5.5.9.  I'm using JDK 1.5.05 and have enabled clustering by commenting 
out the clustering section in server.xml without making any changes to the 
section.
