This means that you have 1 MB of data in one scrap -- each scrap is
processed separetely by pdftex. New sections should not influence it.
(It might be possible that ancient pdftex version (1.21a) you are
using does not flush the data to the pdf file after the scrap is
processed and keeps all the data in the memory. Try to find whether
the file th_formdef.tex reaches 1 MB on the problematic line 47627. If
this is the case try to update pdftex.)

You may also increase the memory pdftex is using in the file
texmf/web2c/texmf.cnf by redefining the variable main_memory.

It might be a good idea to draw one scrap with sections in one file,
especially on the slow computer...
