if an app server is out of the picture, have a look at the following URLs, which contain helpful information on the c3p0 configuration options, especially in the combination with Hibernate:


I'm wondering why you have set idle_test_period to zero:

  | <property name="hibernate.c3p0.idle_test_period">0</property>

I would start off with the values as shown in the sample config on the first link above and thus set it to 100 (seconds). Let us know if you start to see a difference.
