Are you getting bus errors from other programs and weird window and keyboard behavior in GNOME as well? I had something like this happening just yesterday, reading this gave some insight: <a href="https://bugs.launchpad.net/ubuntu/+source/jack-audio-connection-kit/+bug/491329" target="_blank">https://bugs.launchpad.net/ubuntu/+source/jack-audio-connection-kit/+bug/491329</a><br>

Exiting PA (pacmd exit) and deleting /dev/shm/pulse* before starting qjackctl seems to do the trick for me. I upgraded my Ubuntustudio from 9.10, so YMMV.<br><font color="#888888">

</font></blockquote></div><br><div>Raine,</div><div><br></div><div>Thank you. "du -m /dev/shm" shows 320 megabytes of memory locked out by pulseaudio, even after its processes have been killed. So my mileage did </div>
