Not really, just one hint: Netscape is a memory hog, at least under
UNIX. 
I used to keep it open on an 256 MB AIX workstation, and after a few
days it
just crashed because of lack of memory. On startup, it easily grabs 64
MB. This cannot be scaled exactly to an i86 architecture, but you'll get
the idea. 
As emacs is not exactly the most RAM conserving program, you might be
running out of memory.
I'd expect emacs is checking for NULL returns on malloc quite pedantic,
whereas netscape
produces cores. You might cross-check against another RAM hungry program
like word and
Netscape, to see if that gets the same effect. Although, Word can do
that on its own ;-)
And, increase the virtual memory.
