[dpdk-users] Run testpmd application and encountered no free page issues

[Paul Tsvika]

Hi Shreyansh,


Thanks for the reply.

I tried to increase the number from 64 to 230. And the number of 460 is
larger than 442.

However, the error message is the same.

Is there anything I can check here ?


Thanks



Paul
