>Description:
I setteup a jack server using env => JACK_PROMISCUOUS_SERVER=jackaudio
I created group named jackaudio and move users to that group,it works but sometimes it freezes, so bad that I have to reboot. I managed to track down the reason  and made a full description of the problems in several patches...
>How-To-Repeat:
start jackd using /usr/pkg/sbin/jackdaemon -p /var/run/jackd.pid -l /var/log/jackd.log -g jackaudio -s -- -S -r -d sun -P /dev/audio

the program  runs on backgroud, I can use it from several users but sometimes it blocks....

several fixes... look at
