[jboss-user] [JCA/JBoss] - please help mysql datasource timeout problem

Hello, I am using jboss 4.0.2 with a MySQL datasource (shown below) that has the idle-timeout-minutes property set to 10. But, after 8 hours of server uptime, I receive the following error when using connections from this datasource: Communications link failure due to underlying exception: | | ** BEGIN NESTED EXCEPTION ** | | java.io.EOFException | | STACKTRACE: | | java.io.EOFException | at com.mysql.jdbc.MysqlIO.readFully(MysqlIO.java:1913) | at com.mysql.jdbc.MysqlIO.reuseAndReadPacket(MysqlIO.java:2304) | at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:2803) | at com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:1573) | at com.mysql.jdbc.MysqlIO.sqlQueryDirect(MysqlIO.java:1665) | at com.mysql.jdbc.Connection.execSQL(Connection.java:3176) | at com.mysql.jdbc.PreparedStatement.executeInternal(PreparedStatement.java:1153) | at com.mysql.jdbc.PreparedStatement.executeQuery(PreparedStatement.java:1266) | at org.jboss.resource.adapter.jdbc.WrappedPreparedStatement.executeQuery(WrappedPreparedStatement.java:296) | at org.hibernate.jdbc.AbstractBatcher.getResultSet(AbstractBatcher.java:118) | at org.hibernate.loader.Loader.getResultSet(Loader.java:1239) | at org.hibernate.loader.Loader.doQuery(Loader.java:374) | at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:210) | at org.hibernate.loader.Loader.loadEntity(Loader.java:1312) | at org.hibernate.loader.entity.EntityLoader.load(EntityLoader.java:116) | at ... I know that this error will occur if a connection in the pool has been idle for more than 8 hours [default setting] because the underlying connection will go stale. My datasource file is shown below: <datasources> | <local-tx-datasource> | <transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation> | <jndi-name>jdbc/MySQLDB</jndi-name> | <connection-url>jdbc:mysql://localhost/db_name?autoReconnectForPools=true&dumpQueriesOnException=true&useServerPrepStmts=false</connection-url> | <driver-class>com.mysql.jdbc.Driver</driver-class> | <user-name>****</user-name> | <password>****</password> | <idle-timeout-minutes>10</idle-timeout-minutes> | <min-pool-size>0</min-pool-size> | <max-pool-size>25</max-pool-size> | | <exception-sorter-class-name>com.mysql.jdbc.integration.jboss.ExtendedMysqlExceptionSorter</exception-sorter-class-name> | <metadata> | <type-mapping>mySQL</type-mapping> | </metadata> | </local-tx-datasource> | </datasources> I should never have a connection lasting longer than 10 minutes, right? I understand that it might be a bit longer than that because the checker runs on a time interval that is half of the lowest idle-timeout-minutes but, not 8 hours... I would really appreciate any advice you might have to offer. I have searched and searched for a possible cause and have not found any. Thank you very much.
