As I wrote at the end of the long thread on the mailing list:
https://tug.org/pipermail/tex4ht/2023q4/003508.html

(thread starts at https://tug.org/pipermail/tex4ht/2023q4/003489.html)

DVI format is limited to 2^16 pages, and I see no feasible way to change that. Sorry.

I have been working with Michal on this via private email but thought to enter a bug report on this just for tracking and documentation.

I have one large file (57,000 PDF pages) that when compiled with tex4ht (takes 14 hrs), and at about 10% when generating the final HTML pages, it gets XML error and stops.

i.e. the 90% rest of the sections are missing from the final web pages.

I've just send Michal a link to complete self contained ZIP file (450 MB) with instructions how to run as standalone in order to see these errors on his end.

I tried this on latest texlive 2023 on new Linux installation.

I will work with Michal to provide any additional information he needs from me, to hopefully find the cause of this problem.

This happens only on this file. I think may be due to the large size, since the Latex code is all generated by same program and only this file gives this error.
