FWIW, I've been using Mathematica since about version 1.2 and
have many older notebooks created with older versions of
Mathematica. I've yet to find one of those older files I cannot
open or that causes Mathematica to hang or crash on opening. So,
my experience indicates the problem you are seeing is due to a
corrupted file rather than instability in Mathematica.

I believe this problem is inherent in any software such as
Mathematica that can be seen as a general purpose programming
environment. A characteristic of such software is that it is
relatively easy to create code that consumes memory or other
computer resources without bound. While it would be very nice if
Mathematica could trap such problems and give the user
sufficient warning to quit in a graceful manner, I suspect this
can never be without creating significant performance issues.
That is the nature of allowing arbitrary code to be created and run.
