mod-proxybalance

I run apache2 on Ubuntu as a caching load-balancing reverse proxy in front of a group of application servers. I have noticed that the balancer maintains some state for some of the attributes visible in /balancer-manager such as whether an IP is enabled/disabled, load factor, etc.

My site has periods of high (and low) usage, and recently as I added a new server to the working group I noticed that the load balancer picked up the new server but had it set to Disabled. I'm curious where that data is stored, and/or how it is initialized.
