Hi,
Attached, in the hope that somebody will find it useful, is a unified test case for some of the slow consumer / advisory recursion issues, ala AMQ-2533 Right now, this test is very good at reproducing the advisory stack overflow issues that were present in 5.3.0. It's not very good at triggering OOM issues but if it were tuned to run for long enough, that might change. Several tuning constants are present at the top of the test. (This is a little long at 500+ lines but is completely self contained. It's a trimmed and repackaged version of my app code for now - possible to trim it a little more) Nathan Bryant
