Sounds like the app has an infinite loop. Take several thread dump about 10 to 20 seconds appart and look for a thread whose stack trace has not changed (and which is not waiting on an object or input - you can ignore those threads). Once you identify the thread, you can identify the code that caused the loop. If any classes from the "off the shelf" app are in the stack trace, let the developers that wrote the app know about the issue so that they can fix it.
