Tomcat LoadBalancer setup and configuration issue

Have three servers: X, Y, and Z in a Load Balanced configuration - not in a cluster.
Or, we have two servers: X, and Y in a Load Balanced configuration - not in a cluster.
Load Balancer is configured as ACTIVE-ACTIVE.

Windows server 2003 or Windows server 2008
Each runs Apache Tomcat 6 (for Windows)
Apache runs fine - no issues web pages come up fine, customer work great.

We have a corporate mandate that each server is patched and is kept up-to-date each month.  Problem comes in when Server X goes offline, we have to manually restart Apache on Server Y.  Reading in the Apache Tomcat documentation, with a clustered configuration, we should be able to maintain services between the servers without having to restart Apache when one node goes offline.  Yes, I understand a Load Balancer is not a cluster - but this should operate somewhat like one in the sense, if the heartbeat is cut-off, the secondary and/or tertiary servers pick up the load and continue on as normal.

Am I totally missing the mark here?

Within apache worker process definition which presumably how you are load balancing, you need to configure the ping test interval
