DP8 - "Processing" indicator constantly spiking

[bricker]

When I first started using DP8 all seemed well, but now I'm noticing that the "Processing" indicator is constantly spiking when the program is just sitting there not doing anything. I have 16GB of RAM and a 3.2 GHz i3 processor in my iMac, and am running DP in 64-bit mode. Even when I disable all of the VI's and plugins, the problem persists. This in a project with about 20 empty chunks. There are no other big programs running on the computer.

It is an issue because I get some pretty bad audio clipping and stuttering issues whenever the processing meter clips.

What can I look at to figure out what might be causing this issue? It seems to have only happened recently, and it seems to coincide with when I got Rewire to work properly with Live 8 Beta, although the problem happens even when Live isn't open, and even if I quit and re-open DP.

Thanks,

**Update**
Well, I posted too soon. It seems like a hard reset of my computer brought the memory usage down to a normal level. I am still very curious why the issue was occurring, though, so if anybody has any thoughts, please share!

Two things.

DELETE THE DP PLISTS (preferences).

REPAIR PERMISSIONS.

That should fix it. Really.

I'm having the same problem, but it seems less severe than yours. I've deleted plists and repaired permissions, etc, but this hasn't solved it. If I reset the audio device with any change that makes it reload the driver, or restart DP, the problem goes away for a while, and then it slowly returns.

So it's starting to look like a timing/sync problem. I'm trying to isolate it to DP or to my audio interface.
