Hmmm...RAM is pretty cheap now, but anyway, try looking in the Help files
for  Memory Management, and Utilities`MemoryConserve`. As for Linux in
general, I am not a Linux guru by any means, but later versions of the 2.4
kernel have an entirely new virtual memory manager. (See
http://www.byte.com/documents/s=1436/byt20011024s0002/1029_moshe.html )
which is supposed to be much better. (Not surprisingly the old VM creator
disagrees http://linux.html.it/articoli/rik_van_riel_en1.htm .) Of course
FullSimplify can be very memory intensive...perhaps you can do all the
simplifications first, save the results, restart the Mathematica kernel and
continue the calculations? Hope this helps.
