Here is what I'm actually getting.
This output is from right before I left the office yesterday.
[root@kevin admin]# free
total used free shared buffers cached
Mem: 1548264 379112 1169152 0 113372 206988
-/+ buffers/cache: 58752 1489512
Swap: 2096472 0 2096472
Now here is my output when I got into work the following morning.
[root@kevin admin]# free
total used free shared buffers cached
Mem: 1548264 398228 1150036 0 113912 209956
-/+ buffers/cache: 74360 1473904
Swap: 2096472 0 2096472
Is this normal that I would be having less and less free memory? I'm the only that
uses the server so it was running idle all night.
Thanks,
Kevin

Okay folks memory used for buffer, and cache is free memory!!! If you
need to use it the kernel will discard the buffer.
example:
root@sflory tmp]# free
total used free shared
buffers cached
Mem: 514836 508620 6216 0 112976 218312
^^^^ actual free
-/+ buffers/cache: 177332 337504
^^^^^^ free not
counting buffer, and cache

There is no such thing as obsolete hardware.
Merely hardware that other people don't want.
