Hello,
running rhas2.1 with 2.4.18-e.31smp  (stock-redhat) on a rx2600. I noticed 
that the figures from /proc/meminfo and thus top seem to add somewhat 
different to i386:
"Shared" and "buffers" and "free" add up  to only 1.6 GB with 2GB available   
In i386 all three add up to the total available. 
I include two listings. Does that make sense and if so how ? I did search this 
lists archive for hints on "top" and "meminfo" . 

Tia & regards 

Dan
