Description

Use of QueueBrowser without destination memory limits causes AMQ to run out of heap space. Retrieving QueueBrowser elements appears to ignore global MemoryUsage and default browsePageSize of 200. Install default 5.8.0 binary distro. Create 5000 persistent messages in queue and browse to see contents . Shutdown, and change the queue policy entry so that it doesn't limit the destination memory(remove memoryLimit="1mb"). Startup broker, and attempt to view the same 5000 entries. This time the results will not be limited and the broker will run out of heap space. Same occurs if using QueueBrowser programmatically. Works in previous versions as results were limited by page size.
