This sounds like something bizarre is going on with what cyrus chose for
its mmap() method.  (Or the Tru64 mmap is doing something silly in terms
of memory allocation).

Since this didn't really change between 2.0 and 2.1, I don't offhand know
what to blame (though perhaps a change of database formats could do this
also--since skiplist will grow much larger than flat for the same data).
