Memory problem

[Brian Wyvill]

 We are running 2 Iris 3020s and are having the following problem.
These machines say that they have 8 megs of memory on boot up,
but when I wrote a 10 line program to malloc a little over 4 meg
it returns with not enough memory?? Why can't this supposed 8 meg
machine access more then 4 meg at one time?
  Has anyone else run into this? Is there a fix or work around?
