I am using Torque 3.0 in our product for over two years with no such
problems.
following is a snippet from our Torque.properties:
torque.database.default.adapter=mysql
torque.dsfactory.default.factory=org.apache.torque.dsfactory.Jdbc2PoolDataSourceFactory
#torque.dsfactory.default.factory=org.apache.torque.dsfactory.TorqueDataSourceFactory
torque.dsfactory.default.pool.defaultMaxActive=30
torque.dsfactory.default.pool.testOnBorrow=true
torque.dsfactory.default.pool.validationQuery=SELECT 1
torque.dsfactory.default.connection.driver=org.gjt.mm.mysql.Driver
torque.dsfactory.default.connection.url =jdbc:mysql://127.0.0.1/tatabase
torque.dsfactory.default.connection.user = user
torque.dsfactory.default.connection.password = password
#torque.dsfactory.default.pool.defaultMaxConnections=30
#torque.dsfactory.default.pool.maxExpiryTime=3600
#torque.dsfactory.default.pool.connectionWaitTimeout=10
torque.idbroker.cleverquantity=true
torque.manager.useCache = true
Good luck Guy
