I have a multi-channel delay patch that runs beautifully on my G4 PowerBook, but on my dual processor G5 in a very short time (1-5 mins) audio starts sounding ring modulated and then hangs... the UI stops re-drawing and the MaxMSP application has to be force quit (ed?). A friend's machine has to be hard-rebooted after running the patch for a few minutes. If I disable the second processor on my G5 using CHUD tools, the patch runs fine. This is on OS 10.4.5 and MaxMSP 4.5.7. It happens when running in Max, as well as when running as a stand-alone app.

Any ideas about what might be going on? I'm using all built-in objects except for the xsample~ external...
