Computer crapping out at under 50% of CPU limit in Pro Tools. What gives?

Well, I guess now at least I know I'm not crazy for having this problem... Good luck to you guys.

I tried connecting a friend's old mbox 1 that he had used with PT6 (via USB directly into my Imac) instead of the digi003, and the cpu usage issue went away.

That would indicate there was something wrong with Firewire communication.

Are you sure you've disabled firewire networking in the System Preferences>Network control panel?

Yes, the firewire networking is off.

If not a 400>800 connection issue, could it just be a bum FW port on the digi003 or Imac?

I'm bumping this thread because my problem is extremely similar to this. I'm running PT8 on a dual 2.5 G5 with 2.5Gb ram. When I am running a session it is exactly the same error at exactly the same times. With two processors selected, the session reaches max 50% and then the error, and about 85% with one processor selected. In PT 7 I could run the same size sessions with two processors no problem. I'm not using a firewire drive. I'm in the same boat, if the processor was actually being maxed out in a normal way I would be fine with dealing with the inadequacy of the computer.
