Java Ingres DB JDBC连接已关闭且未恢复

我们在Grails应用程序中有一个Hibernate/JDBC连接到入口数据库：

dataSource {
    dbCreate = 'validate'
    url = "jdbc:ingres://xxx.xxx.xxx.xxx:II7/test"
    driverClassName = "com.ingres.jdbc.IngresDriver"
    username = "ingres"
    password = "ingres"
    jmxEnabled = true
    initialSize = 5
    maxActive = 50
    minIdle = 5
    maxIdle = 25
    maxWait = 10000
    maxAge = 10 * 60000
    timeBetweenEvictionRunsMillis = 5000
    minEvictableIdleTimeMillis = 60000
    validationQuery = "SELECT 1"
    validationQueryTimeout = 3
    validationInterval = 15000
    testOnBorrow = true
    testWhileIdle = true
    testOnReturn = true
    jdbcInterceptors = "ConnectionState"
    defaultTransactionIsolation = java.sql.Connection.TRANSACTION_READ_COMMITTED
}

我们的数据库崩溃了，我们不得不重新启动它。从那时起，我们得到了一些错误，尽管我们可以从SQL工具访问ingres db，但Grails应用程序并没有恢复

我们能做些什么？类似于故障时重新连接？

当我们访问页面或通过hibernate访问db的任何其他操作时，以下说明了我们的日志：
