Please help me with pro tools m audio 8 cpu overload!!!!

[Arthur Hendriks]

Yes, upgraded and still that problem. I have no external drive. I really tried everything.
I use Vienna Instruments as a plugin. Even get that message without any plugin active.

But you're not using your system drive for audio correct? You have another drive within the chassis for audio?

[Arthur Hendriks]

Upgrade last week to 8.0.4. At the moment its set on 6 cores and 70 %

[bradch00]

What disk are you writing audio to? The reason I ask is that I had a serious 6101 problem until I switched out my external drive to another one. So you have 6 cores at 70% for RTAS processing and 2 full cores for OS. You have tried 6 cores at 99% and 2 cores for OS, yes?

[Arthur Hendriks]

Hi there. Latest info at this moment:
H/W buffer: 1024
6 cores
CPU limit 70% (tried 99% at 6 cores)
DAE playback buffer level 2 (1500ms)
Cache size Normal
Plugin steaming buffer level 4

Internal audio disk WD 500 Gb 7200 rpm

System activity:

PCI 0%
CPU (RTAS) 9 %
CPU (Elastic) 0%
Disk 5 %
That's it.. (for now ;0))

Hmmm, one last question (I know I have all questions, no answers)... what version of OS X are you on?

[Arthur Hendriks]

No problem :0)
OS X 10.6.4

[bradch00]

I have another PT installation (another disk attached to the same machine) used for testing. I will play around with some of the settings you have and see if I can replicate the problem. Will let you know what I come up with...

[Arthur Hendriks]

Thanks a lot, i appreciate your help.
Cheers Arthur

See my reply from this thread:

I think I may have a lead on possible causes for this error.

Have any of you been removing any of the Mbox 2 or Eleven Rack preference panes, which are installed by default, from your system?

If so - that will cause this error. What's happening is the launch daemon is looking for that preference pane and not finding it, so it will continually be relaunching and using up CPU time. Also it will be writing to the system log file and taking up addition CPU time.

If you encounter a 6101, immediate launch Activity Monitor and look at which processes are taking up the most CPU - do you see 'syslog' in there?

Also, you can launch the Console app and click on the 'Show Log List' in the upper left (unless the log list is already shown). Look for the system.log (under Files) in the left panel and click on it - you may see it continually writing to the log with info about trying to find one of the missing preference panes.

To resolve this issue - if you don't want the preference panes, besides removing the pane, you need to remove the Launch Daemon for the preference pane, located at:

/Library/LaunchDaemons/com.digidesign.xxx.helper.plist (where 'xxx' is the devices preference pane you want removed - for instance 'elevenrack')

If you see other info in Console or Activity Monitor other than what I'm describing, please let me know!
