If you are using DPDK-1.5, it's nice to update to DPDK-1.6, because pcap
pmd of DPDK-1.5 has buffer overflow while receiving  data from a target
device/file. And the issue was solved with DPDK-1.6 (in both intel
original code and dpdk.org code).

Also if multiple processes/threads run on a same cpu, probably, it could
cause a problem like you're facing.

Regards,
Tetsuya
