Hi,
   

   Yesterday i tried to start cdda2wav but somehow it didn't do
anything.
  It didn't die to kill -9 too. Machine was slow but usable.
  vmstat 10 output:

cs field is absolutely ridiculous for my machine.

ps showed cdda2wav & kswapd eating all of processor time. When i tried
to close
netscape, it hang too and joined cdda2wav and kswapd:

I couldn't leave X and had to kill it. After that, both netscape and
cdda2wav were
gone and everything looks normal since then.
I'm running 2.4.3ac3 right now.
