``Inactive'' just means that the page just hasn't been accessed
for a while and is a candidtate for replacement.  However, on a
system without swap, the system has nowhere to send the page if it
is dirty.  The only pages that can always be discarded and reused
are those in the ``Cache'' and ``Free'' categories.

So the bottom line is that you really are running out of memory.
