"TreeCache error after Hibernate sessionFacotry close" To view the discussion, visit: https://community.jboss.org/message/724584#724584 -------------------------------------------------------------- I am using a Hibernate 3.1.13 with jboss-cache 3.2.5 I'm running my application with second level caching enabled and in middle of the application (based on user operation ) I am closing the existing session factory (sessionFactory.close();) and create a new one. Up to this moment my second level cache work fine and after closing and creating new session factory I am getting following error from the Treecache.
