Sun Java System Calendar Server 6.3 Administration Guide

21.8 Using Load Balancing Across Multiple CPU's

By default, load balancing is enabled in Calendar Server. Calendar Server achieves load balancing using the following algorithm: Processes accept one connection out of every n connections, where n is the number of processes.

To disable load balancing, add the service.http.loadbalancing parameter to the ics.conf file and set it to "no". Then restart Calendar Server for the change to take effect.
