How to add confg file to allow UHD drive set priority?

[Nate Duong]

I have Ettus B210 and trying to add 1 line configuration file "/etc/security/limits.conf" which will allow UHD drive to set priority.

So , I typed this command to edit file: gksudo gedit /etc/security/limits.conf and add:

#@student hard nproc 20
#@faculty soft nproc 20
#@faculty hard nproc 50
#ftp hard nproc 0
#ftp - chroot /ftp
#@student - maxlogins 4
@GROUP - rtprio 99
# End of file

I want to stop this warning :

UHD Warning:
Unable to set the thread priority. Performance may be negatively affected.
Please see the general application notes in the manual for instructions.
EnvironmentError: OSError: error in pthread_setschedparam

following this instruction from this link: https://files.ettus.com/manual/page_general.html but I can not stop that message? So I need help from you.

If anyone knows, please help me out.

Thank you.

Looks like the message is harmless:
