The autostart may be the issue. It could be autostarting before limits.conf is read.

I was using the systemd service type startup here: https://yabb.jriver.com/interact/index.php/topic,111505.msg770591.html#msg770591 and it prevented priorities from working. Priorities works when starting MC normally. Now I am trying to figure out the easiest way to start MC on boot.

EDIT: Placed "@mediacenter23" in /home/pi/.config/lxsession/LXDE-pi/autostart, all is well now.

So the systemd autostart is preventing the thread priorities from working?  That is indeed very odd.  I'll need to tinker and see if I can figure out why that should be; the systemd unit definitely waits until after the display manager loads; you'd think the limits would be established by then.

I'm guessing that the limits.conf per user/group settings might require getting past some user login code.

Thanks Bob and Zhillsguy.  changing @audio to pi in the limits.conf worked for me. I now get the RR 99 part, which I wasn’t getting with @audio in the etc/security/limits.conf file.
I hope this fixes my random micro freezes.

I just installed Lubuntu for the Pi available here:

https://ubuntu-pi-flavour-maker.org/download/

Followed the normal MC install instructions for Debian/Ubuntu, all went flawlessly. Seems pretty responsive as well, definitely a usable alternative to Raspbian.
