I have applied the proposed patch and recompiled ports/audio/jack; it
does not help; to debug further, I replaced the binary jackd by a shell
script:


#!/bin/sh

printf "new jackd call:\n" >> /tmp/jackd
echo $0 $* >> /tmp/jackd
/usr/local/bin/jackd.bin $* &
echo $! >> /tmp/jackd

and when a mail arrives the file /tmp/jackd shows:


new jackd call:
/usr/local/bin/jackd -l
39343
new jackd call:
/usr/local/bin/jackd -l
39345
new jackd call:
/usr/local/bin/jackd -l
39347

the PIDs of the zombies are always -1:

39342  2  Z      0:00,01 <defunct>
39344  2  Z      0:00,01 <defunct>
39346  2  Z      0:00,01 <defunct>

i.e. it must be the PID of the shell started by kbiff which let me
think, that the fork/wait in kbiff itself is is causing the problem;
