It might be worth putting a property listener on each AU node for the
kAudioUnitProperty_LastRenderError property, and see if you get any
notifications...

Thanks for the suggestion. I did this and lo-and-behold when the
graph fails none of the units are rendering properly. At least, I
am not getting a notification from them.

Perhaps I need to inform the graph of this? Again, none of these
problems show up on with QT 6.5, only with QT 7.0 installed have
these problems shown up.
I think you can look elsewhere for the problem. We use graphs for
offline processing of chains of AUs, with no problems. We also do
nothing to notify the graph that we are processing offline. This
works as fine in QT 7.0 as it did in QT 6.5 (and prior).
I would recommend going through the chain and adding render notify
callbacks to each unit (using AudioUnitAddRenderNotify); this
should help you determine where in the chain the failure is
occurring.
