did you increase the tile cache size? Otherwise you are not using much
of your RAM and almost all the tile data ends up in the swap file
which is indeed limited to 2GB (see below).

I can definitely tell you that GIMP-1.2 as well as GIMP-1.3 up to
version 1.3.11 have the same problem on whatever platform you use
them. See http://bugzilla.gnome.org/show_bug.cgi?id=74478

I have finally fixed this in CVS last weekend and successfully tested
with the swap files growing to almost 5 GB. The fix will in the 1.3.12
release. If you need it now, you will have to use GIMP from CVS. You
should however note that this is an unstable development tree and
there certainly are bugs in GIMP-1.3.
