Absent a test case that demonstrates the problem it is pretty much impossible for us to diagnose the problem based on the information provided here. Possible ways forward include: - Take a series of 3 thread dumps 10s apart when the problem occurs. Analyse the thread dump for hints to what is going on. - Configure the Tomcat for remote debugging, set a break point for connection borrow and step through the code using your favourite IDE when it stops working. - Take a look at state of the pool(s) via JMX when the problem occurs. The more relevant information you provide, the more likely we are to be able to help.
