I have an installed production system and it got into a state where it could not allocate more database connections. The application is a J2EE application as an EAR file. It uses Derby as the database and uses only JPA access to the database in a CMT. Here is the message from the server:
[#|2008-12-04T06:13:57.800-0500|WARNING|sun-appserver9.1|javax.enterprise.resource.resourceadapter|_ThreadID=33;_ThreadName=RDPConnectionEngineUDP;csemDatabasePool;In-use connections equal max-pool-size and expired max-wait-time.

Reason : In-use connections equal max-pool-size and expired max-wait-time. Cannot allocate more connections.|#]
I am not sure I understand the message or when this problem will occur so any help will be greatly appreciated.
