Yes, you should be reading the second line. > [root@ten-212 ~]# free > total used free shared buffers cached > Mem: 7918844 5478820 2440024 0 111684 5082152 > -/+ buffers/cache: 284984 7633860 > Swap: 9961464 204 9961260 This first line includes all files that are being cached in memory (for faster reading if needed later, for example). That memory will be freed up if needed. The second line doesn't include that cache, so is a better indicator of actual memory use. (And on that first line, "cached" is already part of "used", so your free memory counting the cache is 2440024; it's just provided for informational purposes.) --keith -- kkeller@xxxxxxxxxxxxxxxxxxxxxxxxxx
