             Summary: OOMs are still possible when using clustered web sessions/SFSBs w/passivation
                 Key: WFLY-3180
                 URL: https://issues.jboss.org/browse/WFLY-3180
             Project: WildFly
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Clustering
    Affects Versions: 8.0.0.Final
            Reporter: Paul Ferraro
            Assignee: Paul Ferraro


Currently, the owner of a web session or SFSB is responsible for schedule passivation.  Unfortunately, much to my surprise, infinispan eviction commands are not broadcasted to the cluster, but are local-only.  Consequently, the number of cache entries stored in memory can grow beyond the configured passivation limits, since remote copies of old cache entries are never evicted.
To fix this, we can use the CommandDispatcher to manually broadcast eviction commands to the cluster.
