So check it out:
I can totally reproduce this error on my system with NO audio and NO 3rd party plugs. Just Dverb and Signal Generator with a (heavily) multilayered bus structure.
Here's the session...

My CPU usage has to be at least 65% to see the magic happen, so if you want to try it for yourself and have a monster system, just pile 'em on till you get a dropout.
Curious to see if anyone else has the same results.
And please MUTE YOUR VOLUME. It shouldn't blow anybody's speakers out, but it potentially could!
