Now, two of my FreeBSD boxes are set up about the same, both have 512 MB of RAM, they only differ a little in terms of CPU, mainboard and network components used. Furthermore, both machines use the very same version of FreeBSD - -STABLE as of last Saturday, with a kernel that is also configured about equally (only exception: the two boxes use different NICs and therefore the kernel configuration differs a little in that area.) Let's now come to the IMO strange thing: I just noted that the output I get when running top(1) on these machines differs a little. Not in terms of numbers, but in terms of information shown: The "Mem:" line on my first machine has six fields: Active, Inact, Wired, Cache, Buf and Free. On my other machine, there is no "Cache" field - everything else is the same. Now, what does this suggest? I did not play around with any of the options that set how to displays information. So, is my machine haunted, or am I stupid? *Or* is there actually an explanation what is causing the stuff I have observed and described above, and why it is the way it is? Any suggestions are welcome! I have seen a lot of strange things and found out what caused them, but this one somehow totally confused me...
