The main problem is that your files are so extremely huge. TeX4ht
needs some extra memory, because it declares link destinations for all
sections and for each cut page.

make4ht  -ulm draft foo.tex "mathjax,htm,fn-in,3"

It will produce separate files for sections, but not for subsections.
You should save a lot of memory and compilation time using this.
