[dpdk-users] Failed to remap 2 MB pages

Could it have to do with memory fragmentation? What if you reboot? What if you configure the huge pages on the grub command line so they are allocated at boot?

Subject: [dpdk-users] Failed to remap 2 MB pages

Hi All,

I am getting the error Failed to remap 2 MB pages when I give 32GB of memory to DPDK. I have a 256GB system and it was working for 16GB and I had 8192 number of Huge pages previously. Now for 32GB I have increased it to 16384 entries and I am facing this error. I guess this is not because of the unavailability of physical memory. 

Please correct me if I am wrong,

Thanking You,
