almost 100% of my computer's memory is taken up... why?
here's what I see if I run top and sort by memory:

The biggest app that I have is java which I set to take up 280 mb of memory. But my computer has 512 memory total (as it's shown at the top)... but it's also shown that almost all 512 is taken:
Mem: 512892k av, 503812k used, 9080k free
... My computer seems to be working just fine, but this message doesn't make any sense.. why does it say that 500mb of memory is being used? Also, what's "av" stand for?
Thanks! |
