CMX causing System Overload errors in Logic

In Logic 8.0.2, if I send an audio track to an Aux with CMX inserted and the send is at a level higher than -infinity after the last region, Logic overloads on two cores of my 8-core MacPro, stops playback and gives me the System Overload error message. If the send is set to -infinity before the last region ends, the error doesn’t occur. :astonished:
