function pa_memblock_acquire(). Aborting.


It happens with different applications connecting to PA. pa-mbeq is active and
everytime a stream begins/ends/pauses(corks?), the problem (see above) occurs.

If pa-mbeq connects to alsa it works. If it connects to bluetooth or another
pulseaudio-server via Lan it works not.
I tried another laptop, same debian packages (wheezy) same version, same
configuration. mbeq => bluetooth (same headset) works.

So the problem occurs on one of my laptops and if mbeq connects to bluetooth or
another pulseaudio server..... ?

Thanks for any help!

Jasmin
