Hibernate, C3P0, Mysql — Broken Pipe

Question

MySQL seems to have an 8 hour time out on its connections. I\'m running multiple WARs in Tomcat utilizing Hibernate for ORM. After 8 hours (i.e. overnight), I get broken pip

Answer 1

I've several problem - - C3P0ConnectionProvider was not found - I solve it by using the hibernate c3p0 version

        org.hibernate
        hibernate-entitymanager
        3.5.6-Final
    
          
    
        org.hibernate
        hibernate-c3p0
        3.3.1.GA
    

- I have that wait_timeout issue on mysql. First I set /etc/my.cnf wait_timeout=10 then I changed the Idle time out value to lower than the wait_timeout value which < 10 That solved my problem.
