com.mysql.jdbc.exceptions

Question

After installing 2.2 everything is working, leave it for a few hours and this errors appears, have to restart tomcat6 for it to work again.

Does anyone know what config file I need to correct to fix this?

org.hibernate.exception.JDBCConnectionException: could not execute query

 

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: No operations allowed after connection closed.

 

Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 79,383,279 milliseconds ago.  The last packet sent successfully to the server was 79,383,279 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.
