Hi, I'm using Sonic Software JCA Adapter for JBoss. This message appears in server console log: 10:42:10,015 WARN [JBossManagedConnectionPool] Destroying connection that could not be successfully matched: org.jboss.resource.connectionmanager.TxConnectionManager$TxConnectionEventListener@b7524e[state=NORMAL mc=com.sonicsw.sonicmq.j2ee.jmsra.impl.JMSSessionManagedConnection@1ab6db4 handles=0 lastUse=1227429670062 permit=false trackByTx=false mcp=org.jboss.resource.connectionmanager.JBossManagedConnectionPool$OnePool@1c1b26c context=org.jboss.resource.connectionmanager.InternalManagedConnectionPool@1a8e0bd xaResource=org.jboss.resource.connectionmanager.xa.JcaXAResourceWrapper@17c814d txSync=null] What are possible reasons for this?
