Paul -
With versions prior to 2.9 I was able to run autocorrect on 5000+ mp3s without a problem. (I had up’d the memory defaults basically doubling the settings in the Info.plist).
With 2.9 and 2.9.1, I’ve made the same memory changes, but with as few as 4300 mp3s, I am getting out of memory issues.
Did you change the way memory is used? Are you doing something that is using more?
Once you get that “Out of memory” error, the whole thing shuts down. Are there logs around to send you?
Thanks
