    Jackrabbit shows 'Destroying connection that could not successfully matched' warnings and runs out of connections

    Anonymous User Newbie

      Hey,

       

      I've recently written a small application which's storing things in the Content Repository provided by JackRabbit. Since I ran into the bug described in JCR-3425, I'm using a recent 2.6-SNAPSHOT release built directly from source, deployed as *.rar. The whole thing runs on JBoss AS 7.1.1.

       

      My code is the following, with exception handling stripped:

       

       

      Repository repo = (Repository) new InitialContext().lookup("java:/project/jcr");
      Session session = repo.login(new SimpleCredentials(user, "*".toCharArray()));
      
      Node dir = session.getRootNode();
      doSomethingWithTheInputStream(dir.getNode(...).getNode(Property.JCR_CONTENT).getProperty(Property.JCR_DATA).getBinary().getStream());
      
      session.logout();
      

       

      Upon calling session.logout, the following message appears in my log file whatsoever:

       

      09:10:00,701 WARN  [org.jboss.jca.core.connectionmanager.pool.strategy.OnePool] (http--127.0.0.1-8000-14) IJ000612: Destroying connection that could not be successfully matched: org.jboss.jca.core.connectionmanager.listener.TxConnectionListener@6710ee[state=NORMAL managed connection=org.apache.jackrabbit.jca.JCAManagedConnection@13ccdd8 connection handles=0 lastUse=1355299797231 trackByTx=false pool=org.jboss.jca.core.connectionmanager.pool.strategy.OnePool@1b24dbd pool internal context=SemaphoreArrayListManagedConnectionPool@6afb99[pool=jackrabbit-jca-pool] xaResource=XAResourceWrapperImpl@ee436b[xaResource=session-anonym-148 pad=false overrideRmValue=false productName=Jackrabbit productVersion=2.6-SNAPSHOT jndiName=java:/themis/jcr] txSync=null
      

       

      And eventually, the following (may or may not have to do with how many connections I open) problem occurs.

       

      09:11:37,141 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/project].[Faces Servlet]] (http--127.0.0.1-8000-14) Servlet.service() for servlet Faces Servlet threw exception: javax.resource.ResourceException: IJ000655: No managed connections available within configured blocking timeout (30000 [ms])

                at org.apache.jackrabbit.commons.AbstractRepository.login(AbstractRepository.java:123)
      

       

      Is there any way to avoid aforementioned warnings/exception?

       

      The Jackrabbit resource adapter is configured as follows:
