Yes, kind of like DOS, apparently the kernel does use this low memory for a process handling area as well as buffer storage for TCP and other traffic. I also found a new command that I didn't know of before call slabtop. it shows you the top items using slab. I haven't totally figured out what exactly slab is yet, but I am reading whatever I can find on it.

The question I pose the group is how can I tell how much memory is left in the low memory area that the kernel uses and what is using it?
I have been looking at /proc/slabinfo and playing with slabtop, but I have no clues what I am looking at in theses areas.

Are they talking about physical memory versus swap?
Typically in linux I use the 'free' command to see how much memory is available and used.
