pulseaudio extracted from /var/log/messages for the time that pulseaudio ran
with log-level=4

About once a day pulseaudio crashes with that message.  The machine is usually
idle when this happens except for skype.

'pa_atomic_load(&(b)->_ref) > 0' failed at pulsecore/memblock.c:590, function
pa_memblock_unref(). Aborting.
