> I was trying to use PDFSplit to split a large scanned document into single
> pages. It very quickly ran out of memory. I poked around in the code, and
> it looks to me like the issue is that the splitter code tries to create an
> in-memory model of every single cloned page before writing them to disk. I
> created a patch based off of 2.0.2 that fixes my immediate problem in case it
> is helpful to anybody. All it really does is move the outer processing loop
> to PDFSplit so it can write to disk after each page. This probably isn't an
> ideal fix, but I'm not familiar with the internals of PDFBox to do much more.
