ah, so it is really a Pd bug, and not some bad jack oder system settings?
dunno, but "try a nightly build, i think there are some jack fixes" does not necessarily mean "this is a known issue that was fixed only recently"
best would be to try and report (un)success...
"error: JACK error: cannot lock down memory for RT thread (Cannot allocate memory)"
this error seems to indicate that you are lacking real time priviliges (what's the content of your /etc/security/limits.d/audio.conf?)
This one appears when I load a complex patch. It also crashes Pd:
"tk scaling is 1.3187954309449634 Speicherzugriffsfehler pd_gui: pd process exited"
you could try to produce a backtrace [1]
Funnily, Pd+Jack works with the same patch - as long as I start Pd with alsa, and after loading the patch change the audio to jack.
which would indicate that your patch takes too long to load and jack kicks out Pd....
