    Eviction problems with JBossCache 1.4.0

    K M Newbie

      Hi,

      We are running some tests in JMeter (2 clustered jboss instances) and monitoring the results with JMX (JBoss 4.0.4GA), and we noticed the following behavior:

      jboss-cache 1.3.0

      jboss-cache 1.4.0 GA

      Both are running the same tests, the only change is the version of JBoss Cache jar.

      It seems like eviction stopped working as soon as we upgraded the jar... how come?

      We are using hibernate 3.0.3cr3 (from CVS), optimistic locking, invalidation async. Thanks again.

          To complement the previous post, we are seeing this strange behavior of jboss-cache 1.4 in the logs every time the eviction thread wakes up:

            Hi,

            When the cache starts up, it dumps a list of the interceptors configured into the log. Could you paste this list? Since 1.4.0, all eviction code has been moved to a dedicated EvictionInterceptor.

              The log follows:
