If I send messages (default: persisted) using the default
persistance manager, (rollingLogged), and messages aren't
read fast enough, does that mean that after 1000 unread
messages stack up, the service starts dropping messages
quietly?

Is there a way to fix this (say by increasing the rollover limit) or do I have to move to file or jdbc
persistance managers.

Please forgive my ignorance, I've just started encountering JMS today...
