[xmlblaster] xb_queues table entries

["Joanne" <jlc.xmlblaster.0504 at jambotech.com>]

I've set up xmlblaster to work with Oracle for persistence queues. In my experimentation, I noticed that a new callback row entry into the xb_queues table occurs for each new client login like:

callback_nodemymomclientmrmoose-4
callback_nodemymomclientmrmoose-5
callback_nodemymomclientmrmoose-7

Do these row entries ever get cleared from the table? Even if the client performs a disconnect, I noticed that these row entries remain in the table. I guess my real question is: Is there anything that automatically maintains/cleans this table to remove stale entries?
