Hi Louis

I'm not an expert but here is what I think you need to do based on
my memory of advice I had from Ross Moore.

(1) Go to /usr/local/teTeX/share/texmf/web2c and make a cp of
texmf.cnf called texmf.cnf.bk.

(2) Edit the file texmf.cnf as follows.
In that file search for every occurence of `context' . You should
see lines like:

main_memory.context = 1500000
main_memory.mpost =   1000000
main_memory =          263000 % words of inimemory available; also 
applies to inimf&mp

I think you need to increase the main_memory line to something like
what context has. Maybe instead of changing main_memory you should 
add a line like

main_memory.pdflatex = 15000000

Do this for every memory related parameter that is set for context.

(3) After this I think you should run

texconfig init

Of course an expert would now which of these numbers to change !!

There is a teTeX manual 
/usr/local/teTeX/share/texmf/doc/tetex/TETEXDOC.pdf which
discusses a few of these things.
