Hi,

   When closing jboss using interrupt signal (shutdown hook is enabled properly) with cache enabled TimeoutException is throw for every category defined. I tried to install jboss shutdown hook, configure integration withoud cache manager (I know that it won't work according to docs, but wanted to try everything), modify LockAcquisitionTimeout and wakeUpIntervalSeconds - nothing helps. Errors occur only during shudown. Please help, I don't have any idea what is wrong.

Environment:

• JBoss 5.1 GA
• Hibernate 3.3.2 GA
• hibernate-jbosscache2-3.3.2.GA integration build from Hibernate branch (includes fix for HHH-3818)
• Java 6 b17

Cache config:

• Local mode
• Cache manager with custom config

    <cache-config name="cust-optimistic">

        <!-- Node locking scheme -->
        <attribute name="NodeLockingScheme">OPTIMISTIC</attribute>

        <!-- Mode of communication with peer caches.
       
             INVALIDATION_SYNC is highly recommended as the mode for use
             with entity and collection caches.
        -->
        <attribute name="CacheMode">LOCAL</attribute>

        <!-- Max number of milliseconds to wait for a lock acquisition -->
        <attribute name="LockAcquisitionTimeout">15000</attribute>

      <!--  Eviction policy configurations. -->
      <attribute name="EvictionPolicyConfig">
        <config>
          <attribute name="wakeUpIntervalSeconds">30</attribute>
          <!-- Name of the DEFAULT eviction policy class. -->
          <attribute name="policyClass">org.jboss.cache.eviction.LRUPolicy</attribute>
          <!--  Cache wide default -->
          <region name="/_default_">
            <!-- Evict LRU node once we have more than this number of nodes -->
            <attribute name="maxNodes">10000</attribute>
            <!-- And, evict any node that hasn't been accessed in this many seconds -->
            <attribute name="timeToLiveSeconds">600</attribute>
          </region>
         
            <region name="/_cust/sys/FormControlEntity">
                <attribute name="maxNodes">3000</attribute>
                <!-- 20 min -->
                <attribute name="maxAge">120000</attribute>
            </region>
          <!--  Don't ever evict modification timestamps -->
          <region name="/TS" policyClass="org.jboss.cache.eviction.NullEvictionPolicy"/>
        </config>
     </attribute>

    </cache-config>

Below is a thread dump of one of the exceptions. JBoss Shutdown Hook is the lock owner.
