I know a few > others on the list have come up against this one. Yes, I continue to suspect a UAD/PCI/CPU transfer issue is causing many of these Core Overloads. I have tried freezing instrument tracks to reduce CPU load, in turn hoping this would reduce Core Overloads, which it seemed to (does not eliminate but reduces them). But on your advice I will now try freezing any audio tracks with UAD plugs (especially ones that are resource intensive) to see if that further improves the situation. > Well I had about 3.5 gigs in my G5 and discovered after about 6 weeks > of head banging (and not the good kind) that one of my 512 meg sticks > was friend.

So do I, but I was told by my Mac provider that there is still no such test available.

Yes, the folks at UA are excellent, and I absolutely love the UAD-1 plug-ins. This just seems to be one of those issues that is elusive and may be affected by a combination of conditions. FH
