So, if benchmark_rate can run successfully, maybe try rx_samples_to_file with saving the dev/null or with saving to files in a RAM file system. This will limit your capture depth to the size of the RAM. If this works, then it is a challenging issue to save to permanent storage. Perhaps DPDK will work better at the expense of more complex configuration.
