Hi, This is intentional. In order to increase the amount of contiguous allocation possible to perform in DPDK, you need to adjust the following values in rte_config.h: #define RTE_MAX_MEMSEG_PER_LIST 8192 #define RTE_MAX_MEM_MB_PER_LIST 32768 #define RTE_MAX_MEMSEG_PER_TYPE 32768 #define RTE_MAX_MEM_MB_PER_TYPE 65536 I do not recommend arbitrarily changing them as this is untested, but increasing them proportionally (e.g. multiply all of them by 2 or 4) should not break anything. Thanks, Anatoly
