Spoke to a lovely bloke Renato at Avid today and he suggested this
As discusses during our telephone conversation, the quickest way to troubleshoot DAE Errors -6101 and -9128 is to move all third party plug-ins from the Plug-Ins folder to the Plug-Ins (Unused) folder and test the system in this basic configuration.
If performance will improves dramatically, the next step will be to gradually move your plug-ins back to the Plug-Ins folder.
When performance will degrade again, then you will know which plug-ins might have issues and investigate for possible updates or known issues with the plug-in manufacturers.
Let us know how your testing progresses,
So I will do this and report back. Hopefully this info on troubleshooting these particular DAE errors will help others in the same boat too.
