Hi Gautam this is not related to hugepages (actually hugepages reserve physical memory, thus they can affect allocation, however in this specific case it was due to a limit in the pf_ring buffer size). Please note I just pushed a patch to handle this case resizing the buffer size when limit is exceeded, please check if it’s working for you and let me know.
