I did some tests, one with a time-to-live of 20 seconds and one with a time-to-live of 
120 seconds. When the time-to-live is 120 seconds all requests (approx. 1600 in 8 
minutes) are handled by a MDB. But with 20 seconds approx 25% expire on the topic and 
are therfore never handled by a MDB. 
I configured that 1000 MDBs can exist. This should be more than enough considering the 
fact that one request is handled by a MDB in 2 seconds. 

Any idea why 25% never get handled by a MDB with a time-to-live of 20 seconds? is the 
JMS provider not capable of handling more than 3 messages sent to a topic? Or does it 
take some time for the MDBs to return to the pool?
