Hi James, Nicholas,
I still bet it's someone holding too many file descriptors open.
Nicholas, when you said this, "but I have forced the thumbnail
creation to have at most 10 files opened at the same time", what did
you mean? You can see what files your process has open using the
lsof command line tool. Use that to check what files you have open.
lsof -p <pid>
If you find that the problem is files staying open longer than you
want, you may be able to work around the issue by bringing the data
into the process with a method like +[NSData dataWithContentsOfURL:]
(I don't see a CF equivalent, but I may be going blind)
It's just hidden in the Core Foundation References:
CFURLCreateDataAndPropertiesFromResource() from Core Foundation URL
