Ubuntu 13.10, jdk1.7.0_40, Mysql5.5
Hibernate plugin connections create 2 connection per database update but never removes them.
Hibernate session is not close.
Hibernate configuration:
<property name="c3p0.max_size">10</property> <property name="c3p0.min_size">2</property> <property name="c3p0.timeout">1800</property> <property name="c3p0.max_statements">50</property> <property name="connection.autocommit">true</property>
The problem is that max connections overrides defined value in hibernate (10) I have 12 (If I continue I have 2 connection for each register Job...). Every new Job registered with Audit2db retrieves 2 new connections.
$ echo "SHOW PROCESSLIST" | mysql --user=jenkins --password=jenkins

The value representig timeout 1800 (secs) doesn't remove sleep connections.
I think there is another value like `idle_test_period` that hast to be set (if I've understood the meaning) to remove idle connections.
Or the problem is that hibernate connections have never been closed
Thanks!
