We are using JBossCache with Tomcat 6 on 4 nodes, each node has JBossCache in same JVM as tomcat. I believe, CAS uses SimpleTrigger to fire off the clean up job, so first step would be to increase the job interval on the Trigger to some realistic interval based on your usage. Second, what we have done to prevent every node firing off clean up job at the same time, using CronTrigger and set different cron expression on each node through properties file so that one node out of 4 is running cleanup job every 30 minutes, each node runs clean up job every 2 hours but configured differently so that none overlaps.
