[arch-proaudio] RT-thread issues after update
Hey hey, after a system upgrade, two days ago, some JACK clients present me with the following warning: cannot lock down memory for RT thread (Cannot allocate memory) This includes mpv and jalv from the standard Arch repositories and Yoshimi from git (not even AUR). Yoshimi has allso been updated since the upgrade. All clients appear to work fine after that, but I haven't given them stress testing. What can it be? Do I need to worry? Can I fix it? Perhaps a config issues somewhere?

Hi Jeanette, is the "realtime-privileges" package installed? https://www.archlinux.org/packages/community/any/realtime-privileges/ If not, then install it, add your user to the group "realtime", log out and in. If this shouldn't be the issue, is 99-realtime-privileges.conf the last config providing the memlock configuration or does another package follow and override the setting? $ grep memlock /etc/security/limits.d/* /etc/security/limits.d/10-gcr.conf:@users - memlock 1024 /etc/security/limits.d/99-realtime-privileges.conf:@realtime - memlock unlimited A memlock value in /etc/security/limits.conf is null and void, if any package should have "dropped" something counterproductive to /etc/security/limits.d/. An admin needs to check this after _each_ upgrade.

Yesno. We had a discussion in September 2018, but David announced it earlier in 2018. You seem not to have updated jack from the repositories for a while. IIRC jack already dropped the settings for the "audio" group to limits.d and it was removed from the package around September 2018, so installing the "realtime-privileges" package was one solution.
