Mark Callaghan, "Logic Pro 7 system overload - can anyone help" #40, 05:06pm Mar 20, 2005 CDT
The trouble with 'system overload' errors is that there are too many possible causes, and even in at thread like this, many of them don't get mentioned.
One thing just sprang to mind, that, even though it probably doesn't apply. may point you down untried avenues.
Some time back the demo of the iDrum AU would cause these after it expired.
It would be worth sifting your AUs and seeing if one of them were the cause.
Also, if you tested with on plugins instantiated in the song, double-check in Audio Configuration to be sure there are no plugins inserted in channels which are not present in the environment.
btw, do any of the people experiencing this have Pluggo, or Waves installed ?
