OK, I'm making a system to upload photos to a gallery. I'm using filereference, and it's working alright. I can upload like 20 files fine sometimes.. but when I do like 50, it starts giving me errors on over half the files.

The error is: Error #2044: Unhandled IOErrorEvent:. text=Error #2038: File I/O Error.

This may be a php error, or server error, I'm not sure. Because the file isn't even uploading at all.
