There are two other possibilities:

1. You webapp leaks connections

While it is possible, your connection pool should be complaining about
that. Have you enabled removeAbandoned and logAbandoned for your
connections? I highly recommend it -- especially in production.

2. The DataSource is leaking connections on reload

I think this is unlikely to be the case, as Tomcat is lazy about
DataSource-creation: when you reload your webapp, it actually uses the
existing DataSource that was created for the first instance of your
webapp. Actually, unless you intentionally grab-and-shutdown the
DataSource in a ServletContextListener's destroy() method, the
DataSource will not be shut-down on undeploy/reload/etc.
