I once had a setup of "Gallery", a PHP based photo gallery in a 4 web server configuration. Infront is a Cisco Global Load Balancer (The setup is mainly used for a Coldfusion App). Whenever a user is logged in and after several requests, the session would time out, apparently, the next requests goes to another web server. It means the web server has a different set of sessions. I know the Cisco CSS can handle stickyness, but what I did was, had a common NFS share for PHP sessions (usually /tmp). The idea is to have a common data store for PHP sessions (filesystem/mysql/etc).
