[texhax] Tex capacity exceeded

[blasetti at tasc.infm.it]

Hi, 
I'm writing my master thesis with pdftex and this evening I got 
the "TeX capacity exceeded" error.
I copied hereafter the last part of my .log file;
what should I do? Should I ask a wizard and how?
 
Thanks, 
 
Cecilia

If you really absolutely need more capacity,
you can ask a wizard to enlarge me.
