Description

Steps to reproduce -

 

1. Start the Qpid Dispatch router
2. Run the following script that creates a bunch of addresses
3. for i in `seq 1 6546`; do echo "{\"prefix\":\"address-$i\",\"distribution\":\"balanced\"}" | qdmanage CREATE -type=org.apache.qpid.dispatch.router.config.address --name address$i --stdin; done
4. now run qdmanage QUERY --type=address
5. You will receive a Data error (-10)
