[jboss-user] [JBossCache] - org.jboss.cache.lock.TimeoutException thrown in second insta

When we startup another one of our web applications on a second instance in a cluster we get an org.jboss.cache.lock.TimeoutException thrown by org.jboss.cache.lock.IdentityLock.  It seems that IdentityLock is attempting to acquire a WL when attempting to cache the query below but there is already a lock on the node /org/hibernate/cache/StandardQueryCache/sql, probably in the first instance.  This application is running on Resin 3.1.2.  We are using Hibernate 3.2.3 and JBoss cache 1.4.0.SP1.  We have Hibernate configured to use a query and second level cache which is org.hibernate.cache.TreeCacheProvider, the JBoss TreeCache.  We have the JBoss TreeCache to use the pessimistic locking scheme, the node isolation level is REPEATABLE_READ and the cache mode is LOCAL.  

How do we resolve this problem?  

Please let me know if you need further information from me.
