I don't remember the exact setting name but have you configured c3p0 to validate connections before checking out? It is usually done by doing a test sql like select 1 from dual or....

I don't see where that testOnBorrow is going. Take a look at this: http://www.hibernate.org/214.html. I like the testConnectionOnCheckout setting. Do you have to wait for a day to see if this helps you?
