jack_capture-0.9.73-5.3-x86_64 fails in TW

I just upgraded tumbleweed, jack_capture complains
it cannot allocate memory, saves a useless noise file.
Same story with Leap-15.2

Code:

~> jack_capture
Cannot lock down 86611866 byte memory area (Cannot allocate memory)
>>> Warning. Could not set higher priority for a SCHED_OTHER process using setpriority().
Cannot use real-time scheduling (RR/5) (1: Operation not permitted)
JackClient::AcquireSelfRealTime error
>>> Recording to "jack_capture_04.wav". Press <Return> or <Ctrl-C> to stop.

Looks like an error in jack_capture for me. Either file a bug report, or wait for a new version. Alternatively you could install an older version or do a "snapper roll back" if the program is installed somewhere under / (root directory) on a btrfs partition.

Happens when I have qsynth, rosegarden + audacity
running, dropping audacity fixes. Haven't tried
with only qjackctl and audacity yet.

Okay, good for you. Still, shouldn't happen...
