    • Method Detail

      • setScavengeZombieSessions

        public void setScavengeZombieSessions​(boolean scavengeZombies)
        Control whether or not to execute queries to find "zombie" sessions - ie sessions that are no longer actively referenced by any jetty instance and should be expired. If you use this feature, be aware that if your session stores any attributes that use classes from within your webapp, or from within jetty, you will need to make sure those classes are available to all of your hazelcast instances, whether embedded or remote.
        Parameters:
        scavengeZombies - true means unreferenced sessions will be actively sought and expired. False means that they will remain in hazelcast until some other mechanism removes them.
