The first thing DPDK initializes is a log mempool, and since it creates a tailq, it reserves space in rte_malloc heap before allocating the mempool itself. By default, rte_malloc allocates way more space than is necessary, so under some conditions (namely, overall memory available is low) this results in malloc heap eating up so much memory that log mempool is not able to allocate its memzone. This patch fixes the unit tests to account for that change.
