Eh? 500m each? WT* are you doing with your Apache config?

Nope. Have a look at SHR, you can subtract all that too. Even then it's 
probably over; try some experiments with ps and adding up what it says:

[john at hole ~]$ ps -e --no-headers -o vsz|(j=0; while read i ; do j=`expr 
$i + $j` ; done ; echo $j)
882096
[john at hole ~]$ ps -e --no-headers -o rsz|(j=0; while read i ; do j=`expr 
$i + $j` ; done ; echo $j)
414288
[john at hole ~]$ free
              total       used       free     shared    buffers     cached
Mem:        524432     518904       5528          0      14684     215960

Swap:       524280        560     523720


or on another box:

[john at out ~]$ ps -e --no-headers -o vsz|(j=0; while read i ; do j=`expr 
$i + $j` ; done ; echo $j)
4060412
[john at out ~]$ ps -e --no-headers -o rsz|(j=0; while read i ; do j=`expr 
$i + $j` ; done ; echo $j)
1001584

Doesn't make sense to me...

Cheers,

John.
