we are crashing with "too many open files" on PDFTeX from TeXlive. The object id where this happens is 513 or so, and it would be my guess that PDFTeX keeps image files open as long as it has not yet shipped them out.

It would appear that the system limitations of win32 are much larger, so I suspect the runtime with which TeXlive2007 has been compiled.

Does anybody have a good pointer to where I might look for further information? This is quite a bad roadblock for us.

I believe the W32 binaries in TL were built by Akira using MS Visual Studio tools, but I don't know whether/how this limit can be controlled there.

See other mail on this: it would appear to be easy to fix this (namely: bump the number to 2048) in the sources.

As a workaround, have you tried alternatives such as generating DVI output and then running dvipdfmx? It's possible that might handle things differently.

Far too many PDFTeX specific features in use, I am afraid. That road is not open to us at the moment. -- David Kastrup
