We're using JBossCache, and have recently upgraded to CAS 3.2. We have been experiencing some stability problems during our more vigorous load-testing scenarios, (16+ virtual users in JMeter). While our single-server instance can handle this load without problem, our clustered configuration experiences a slow degredation over time (10+ hours) that ends with a large number of replication errors.
We have an extra complication in our configuration, however. We are using the JAASAuthenticationHandler to authenticate to a Kerberos KDC. There is a known memory leak in Sun's implementation which Andrew Feller pointed out. We've been able to ameliorate the memory leak somewhat but it is most likely a contributing factor to our problems. I'm retooling a pair of servers to look specifically for memory and GC issues, which should hopefully shed some light on our problems.
