Hello all, We have launched a new website www.findbestopensource.com which lists the best opensource product across platforms. We are using hibernate and MySQL and c3p0 as connection pool provider. I am getting the below error very frequently. Could you please guide me. com.mysql.jdbc.exceptions.jdbc4.CommunicationsException MESSAGE: The last packet successfully received from the server was 45,172,983 milliseconds ago. The last packet sent successfully to the server was 45,172,993 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.
