All,
The Mbean for a JDBC datasource that uses the commons-dbcp-1.2.1.jar library
builds up on one server. The other server is okay. They run the same code.
We are using Tomcat-7.0.23.
They are both RedHat Linux servers
What could be causing this anomaly?

The term "Application Server" predates JEE and EJB. I would call Tomcat an App
server since it "processes server-side business logic" (i.e. you don't need
EJBs to process business logic and it's sometimes a bad idea anyway.)
