    Evict all nodes from a cache


      Hi friends, I've got this message while I am trying to evict all nodes from a cache, but finally the nodes are evicted from memory so I don't know what does it means.

      12:38:23,781 ERROR [LockInterceptor] entry for transaction <null>:3 not found (maybe already committed)
      12:38:25,859 WARN [LRUAlgorithm] evict(): Node not found with this fqn: /META Could have been evicted earlier already
      12:38:25,875 ERROR [EvictionTimerTask] run(): error processing eviction with exception: org.jboss.cache.eviction.EvictionException: LRUAlgorithm.removeFromQueue(): internal error. Can't find fqn in nodeMap. fqn: /META will reset the eviction queue list.

      Does anybody know what happens with this???? I have been looking for a similar problem in the forum and I haven't found anything.

      I am working with Jboss 4.0.1 and JbossCache 1.2 and I am calling the evict method in the following way:


      is it ok??

      This is the mbean config in -service.xml:

      <mbean code="org.jboss.cache.TreeCache"
       <attribute name="JndiName">/treecache/TreeCacheB</attribute>
       Configure the TransactionManager
       <attribute name="TransactionManagerLookupClass">org.jboss.cache.JBossTransactionManagerLookup</attribute>
       REPEATABLE_READ (default)
       <attribute name="IsolationLevel">SERIALIZABLE</attribute>
       Valid modes are LOCAL
       <attribute name="CacheMode">LOCAL</attribute>
       Just used for async repl: use a replication queue
       <attribute name="UseReplQueue">false</attribute>
       Replication interval for replication queue (in ms)
       <attribute name="ReplQueueInterval">60000</attribute>
       Max number of elements which trigger replication
       <attribute name="ReplQueueMaxElements">100</attribute>
       The max amount of time (in milliseconds) we wait until the
       initial state (ie. the contents of the cache) are retrieved from
       existing members in a clustered environment
       <attribute name="InitialStateRetrievalTimeout">5000</attribute>
       Number of milliseconds to wait until all responses for a
       synchronous call have been received.
       <attribute name="SyncReplTimeout">10000</attribute>
       <!-- Max number of milliseconds to wait for a lock acquisition -->
       <attribute name="LockAcquisitionTimeout">30000</attribute>
       <!-- Name of the eviction policy class. -->
       <attribute name="EvictionPolicyClass">org.jboss.cache.eviction.LRUPolicy</attribute>
       <!-- Specific eviction policy configurations. This is LRU -->
       <attribute name="EvictionPolicyConfig">

       <region name="/_default_">
       <attribute name="maxNodes">5000</attribute>
       <attribute name="timeToLiveSeconds">1000</attribute>

       <attribute name="CacheLoaderFetchPersistentState">true</attribute>

      Thanks all.
