Hi Team,

I am using CX-7 Card, I wanted to test pktgen application, I am facing issue while executing application.

rte_eth_rx_queue_setup: err=-12, port=0, Cannot allocate memory

Could you please let me know how to fix this.

Hi,

Thank you for posting your query on our community. The error usually indicates a system memory configuration issue. You may want to check the following:

  1. memlock limits – Verify ulimit -l is set high enough or unlimited.
  2. Make sure hugepages are configured and mounted correctly (/proc/meminfo should show HugePages > 0).

If the issue continues, please submit a support ticket for further troubleshooting along with a sysinfo snapshot. The support ticket can be opened by emailing " Networking-support@nvidia.com ". Please note that an active support contract would be required for the same. For contracts information, please feel free to reach out to our contracts team at " Networking-Contracts@nvidia.com "

Thanks,
