While bouncing to disk, I get this error:

The Operating System held off interrupts for too long.
If this occurs frequently, try increasing the “H/W Buffer Size”
in the Playback Engine panel. (-6093)

The Digidesign website and suggests several workarounds, including:

  • Reduce CPU Usage to “below 95%”
  • Connect Digi 002 to FireWire port on Mac G5’s front panel
  • Reduce number of active plugins

What works for me:

  • Quit ProTools, re-launch, and try again (works sometimes)
  • Connect Digi 002 to FireWire port on Mac G5’s front panel
