Hello Kim,

Try Yoshimi. ZASFX is notorious for generating xruns.

89 is too high, it's better to run JACK with a prio around 70. Now
JACK's watchdog thread I running prio 99 which might cause problems with
other processes running that prio.

Yoshimi doesn't suffer from this issue either.

They should be commented out in your /etc/security/limits.conf file (or
don't exist at all in that file) but exist in your
/etc/security/limits.d/audio.conf file.
The lines used to get added to the limits.conf file but recently a lot
of distro's moved to adding them to the audio.conf file.

JACK parameters alone won't help you set up an xrun free audio
