[Qt-interest] Too many files open error on Mac OS

[Scott Aron Bloom]

But at each zoom, you are only showing 300 images at different zoom levels right?

Since it sounds like you are having to read them in to show them, why not close them after each rendering and reload them in when necessary...

Storing them in QImage will make the system dead because of not enough 
RAM for it. Some images are 10000x10000 pixels in size. So each file 
stores pyramid of tiles with different zoom levels. And each time, when 
i render, i read only needed tiles from needed level.
