                t.schedule();
                // NMS-5593 shows 10 provisioning threads all waiting on these
                // latches which is probably exhausting the thread pool
                t.waitFor();
                LOG.info("Finished scanning node {}/{}/{}", getNodeId(), getForeignSource(), getForeignId());
