 What's wrong with this?
 OK 12347M is big, but not a problem for alphas.
 It could be that this is memory mapped space for your graphic card and
 likely to be an absolute correct value.

 Well having 21213936K active is clearly wrong.

 What's wrong with those values?
 That's addressspace not physical memory.
 Alphas have plenty of addressspace no need to be thrifty with it.
