Hi Martin,

I try various rt priority settings without any success, dropouts are
still here.

I think part of your problem comes form : 
zombified - calling shutdown handler
To avoid this you can can try to increase the jackd timeout watchdog
with option -t 5000 or disabling  client zombification with option -Z.

Which version of jackd do you use?

All the best
