[development][dpdk] dpdk与CONFIG_RTE_MAX_MEMSEG有关的错误

 

dpdk程序无法启动, 错误如下:

EAL: Requesting 2106 pages of size 2MB from socket 0
EAL: Requesting 1990 pages of size 2MB from socket 1
EAL: Can only reserve 2701 pages from 4096 requested
Current CONFIG_RTE_MAX_MEMSEG=256 is not enough
Please either increase it or request less amount of memory.
PANIC in rte_eal_init():

因为内存的碎片化比较严重,或内存占用比较多. 重启后可以正常启动.
