I  have the following situation, five SQL commands of JBoss Messaging are  running non-stop, making an average of 800 commands every 5 seconds. The  commands are: INSERT_MESSAGE_REF=INSERT INTO JBM_MSG_REF (CHANNEL_ID, MESSAGE_ID,  TRANSACTION_ID, STATE, ORD, PAGE_ORD, DELIVERY_COUNT, SCHED_DELIVERY)  VALUES (?, ?, ?, ?, ?, ?, ?, ?) INSERT_MESSAGE=INSERT INTO JBM_MSG (MESSAGE_ID, RELIABLE, EXPIRATION,  TIMESTAMP, PRIORITY, TYPE, HEADERS, PAYLOAD) VALUES (?, ?, ?, ?, ?, ?,  ?, ?) UPDATE_ID_IN_CACHE=UPDATE JBM_ID_CACHE SET JBM_ID = ? WHERE NODE_ID = ?  AND CNTR = ? DELETE_MESSAGE=DELETE FROM JBM_MSG WHERE MESSAGE_ID = ? AND NOT EXISTS  (SELECT JBM_MSG_REF.MESSAGE_ID FROM JBM_MSG_REF WHERE  JBM_MSG_REF.MESSAGE_ID = ?) DELETE_MESSAGE_REF=DELETE FROM JBM_MSG_REF WHERE MESSAGE_ID=? AND  CHANNEL_ID=? AND STATE='C' Running a profiler on the application, 428.156 occurrences were recorded  for each command in 140 minutes and 7736 messages were delivered. In  this profile, I saw that commands are executed from a  ThreadPoolExecutor$Worker.run. This process is extremely active in Oracle and there is something wrong  with it, because even without traffic and no message, this high number  of commands are still executed. I separated the datasources for each component and saw that the  datasource is used in mbean <mbean  code="org.jboss.messaging.core.jmx.JDBCPersistenceManagerService"  name="jboss.messaging:service=PersistenceManager"... at  oracle-persistence-service.xml. Have someone an idea what could be causing this problem or if there is  any configuration that can stop this thread or even better, solve the  problem?
