I've been testing the file uploader for my site, and it's been working great for images/small files. After trying a 6.4MB .ogg, however, I've been receiving a memory error and the site crashes. Iterating through the req.files to see if the file is arriving does not show a result, assuming it makes it that far. The memory error handler is functioning properly for everything else.
