When using systemd to start the service, use systemd directives to set the limits. systemd won't start PAM session for this service, so /etc/security/limits.conf is not used. Try adding: LimitRTPRIO=95 LimitMEMLOCK=infinity to the [Service] section of your jackd.service file. See `man systemd.unit` fro more info on setting the limits in a service file.
