I assume you mean Xen's memory usage. I am showing 141MB free out of 
8112MB total.  Our scripts to add accounts don't allow adding more 
accounts then there is memory for, we actually leave about 128MB as a 
buffer. 
That's a bit odd then. If you don't explicitly specify dom0's memory 
allocation at boot time then you should end up with 128MB 'slack' left 
unallocated. And that should all be <4GB. 
If you are giving dom0 all of memory on boot, and then reducing it 
later, that could be a problem (dom0 may end up giving back only memory 
>4GB).
