When I was trying to run the Regex sample from File Scan :: NVIDIA DOCA SDK Documentation, this error came and I did not find anything useful on the webpage. Can anyone help me out?

Hi,

Can you please check if:

  1. mlx-regex is running
    #systemctl status mlx-regex
  2. Huge pages were allocated for regex engine
    #sudo echo 2048 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages

Regards,
Chen

Hi, thanks for your reply.

I have checked the regex engine is active and the huge pages are also allocated.
What else could be the reason?

Hi,

Can you please share the full output of “systemctl status mlx-regex” on the DPU?

Thanks,
Chen

Here it is.

I would suggest checking the permissions based on the warning at the bottom and restarting mlx-regex or a power cycle.

I somehow managed to eliminate the warning and then restart the regex engine, however, the new error comes, and I do not know what to do with it.
