Same thing I see in the same address neighbourhood.  How much memory and
swap do you have?

Mine runs www, Radius and PostgreSQL.  I suspect that the actual bug has
nothing to do with the actual programs running but rather with the amount
of activity.

I wrote a program to allocate lots of memory and write something in it
and watched with top -osize while it chewed up 127M of memory.  At that
point it starting failing to allocate but before that it accessed swap
so my original thought that there was something wrong with swap functions
seems to be incorrect.  I am really at a loss.
