Cake/PHP 1.2.6 Caching Consulting

This position absolutely requires an expert in the internal caching mechanisms in Cake/PHP 1.2.6. I am trying to place a cake/php app behind a load balancer and am seeing different results between the load balanced app servers. I believe the issue lies in the application caching and need some assistance in solving this complex problem. It may take an hour or it may take 20 hours, I don't know. A secondary requirement is expertise in memcache/memcached. If you have implemented memcached in a cake/php environment, there will be more hours for you to help me implement the same in my environment. Thank You!
