Hi,
Now that I am trying to run jack1 (instead of jack2), I see that my
clients get zombified very fast.
(Typically even before doing anything useful.)
The JACK wiki points this out as a difference (that jack2 is more
tolerant), but it also says that this behaviour is configurable.
Well, I tried to, but without success.

======================
As you can see, I started jackd with the --nozombies parameter.
Meanwhile, wine/wineasio/kontakt says:
=======================
jack_client_thread zombified - exiting from JACK
========================

Of course, ideally, I would not get xruns; I intend to tune my system
(wine-rt, etc), but still,
how do I configure jack1 not to zombify the problematic clients?
(The exact version of jack1 is svn revision 4538, which is the latest
version in Debian.)
Thank you for your help:
Kristof
