Database connection problems after 8 hours

Hello everyone.
This is a recurrent topic I know, but I have not been able to find a solution for it after reading a lot about it on the web.
How can we make Grails work after 8 hours of users' inactivity?
I am using Grails+MySQL+GlassFish
In my Grails project I use Domain Classes handled by Hibernate which make use of the MySQL database.
I also make use of an Utility Class to make direct queries to the MySQL database.
For the c3p0 pool, my "resources.groovy" file looks like this:
// Place your Spring DSL code here
import grails.util.GrailsUtil
import com.mchange.v2.c3p0.ComboPooledDataSource
import org.codehaus.groovy.grails.commons.GrailsApplication
import org.codehaus.groovy.grails.commons.ConfigurationHolder as CH
beans = {
if (GrailsUtil.environment != GrailsApplication.ENV_TEST && CH.config.dataSource) {
dataSource(ComboPooledDataSource) { bean ->
bean.destroyMethod = 'close'
user = CH.config.dataSource.username
password = CH.config.dataSource.password
driverClass = CH.config.dataSource.driverClassName
jdbcUrl = CH.config.dataSource.url
initialPoolSize = 10
minPoolSize = 10
maxPoolSize = 50
maxStatements = 240
maxConnectionAge = 60 * 60 * 2 // 2 hours
maxIdleTime = 60 * 60 // 1 hour
idleConnectionTestPeriod = 240
testConnectionOnCheckin = true
testConnectionOnCheckout = true
automaticTestTable = "c3p0_test"
}
}
}
My "DataSource.groovy" file has the following:
dataSource {
pooled = true
driverClassName = "com.mysql.jdbc.Driver"
dialect = "org.hibernate.dialect.MySQLInnoDBDialect"
username = "*****"
password = "*****"
autoreconnect = true
useUnicode = true
characterEncoding = "utf-8"
}
hibernate {
cache.use_second_level_cache=true
cache.use_query_cache=true
cache.provider_class='com.opensymphony.oscache.hibernate.OSCacheProvider'
}
The url string I use here is:
url = "jdbc:mysql://localhost:3306/mydatabase?autoReconnect=true&useUnicode=true&characterEncoding=utf-8"
And well... after 8 hours I get the known-by-all message "Broken Pipe":

How are people making Grails work after 8 hours??
Everyone should experience these problems too...
Any help will be greatly appreciated.

** END NESTED EXCEPTION **
There after, I get other sort of errors like:

org.hibernate.AssertionFailure: null id in SearchInfo entry (don't flush the Session after an exception occurs) at org.hibernate.event.def.DefaultFlushEntityEventListener.checkId(DefaultFlushEntityEventListener.java:78)
How are people making Grails work after 8 hours??
Everyone should experience these problems too...
Any help will be greatly appreciated.
