Tomcat server stopped after 12 hrs

hi,

i have developed a jsp web application using struts framework. the application is deployed in Window NT server, MySQL db.

everyday the server is stopped automatically. i have to restart the application now and then (say 12 or 10 hrs differene)... when i look into the tomcat logs details...sometime i could see the below error,

STACKTRACE:

java.sql.SQLException:Communication link failure: java.io.EOFException, underlying cause: null

ORjava.net.ConnectException: Connection timed out

please suggest me what could be the problem...?

i use hibernate db connection... something like,

<hibernate-configuration>

<session-factory>

<property name="connection.url">jdbc:mysql://localhost:3306/test_db</property>

<property name="dialect">net.sf.hibernate.dialect.MySQLDialect</property>

<property name="connection.driver_class">com.mysql.jdbc.Driver</property>

even now i don't know wether it is because of mysql database problem or tomcat server stopped problem....
