Re: Question

That error message indicates the box doesn't have enough RAM for
PF_RING to allocate its memory.  Are you sure you're not low in RAM
for the box?  That might also be a product of using PCAP_MEMORY=6120.
Try removing the environment variables as they shouldn't be needed
anyway when using PF_RING (as the modprobe.conf settings control it).
