I will post the output from free later. I rebooted recently, so the usage is not quite up there yet. However, I think that your free output is rather alarming too. You should not have 500 megs used, unless you are say, running a server with many, many concurrent connections. You are allready using swap space too. Reboot your computer and see how much memory is used right away. As for the caches, I thought that those were referring to the CPU caches. If the numbers refer to bytes (vice kilobytes), mine totals to 640K. If the are KB, then maybe you are on to something. Fwiw, the man page isn't very clear on it.
Thanks for replying though. Know of any good linux memory tools out there?
