DPDK Ring cannot reserve memory

Hi,

I'm fuzzy testing an NFF-Go application. When fuzzing it initially I got errors like:

EAL: Cannot create lock on /var/run/dpdk/rte/config. Is another primary process running?

The errors were due to the fuzzer (even with just one worker) running the binary multiple times before the waiting for the previous process to finish. I read about the --proc-type=auto flag, which felt like it could help here. However, I am currently getting errors like:

RING: Cannot reserve memory

Could it be NFF-Go related problem? Or maybe there are other flags I should pass to DPDK EAL?
