I use pdftk server to automate various tasks. Recently I ran into a problem where pdftk crashed while merging a large number of pdfs with the error window:
Fatal error in gc: Too many heap sections
After receiving this error I've run some tests to confirm that this same error will happen, regardless of what task pdftk is doing on pdfs, when its memory usage exceeds 512Mb.
I was hoping someone could help me understand what this error means, and if there's a way to set up pdftk to handle these larger jobs?
If it's just a limitation of the program, does anyone have a suggestion for a similarly functioning program without this limitation?
So I know it's not perfect, but I just wrote my own implementation using iTextSharp to fulfill my requirements. If anyone else runs into this post and needs it, it's available at this github link under the AGPL license.
