What are you trying to accomplish?? A certain small amount of memory is
allocated by the kernel to build the /proc filesystem. It is not using
320 MB of ram. If it was you would not have any ram to run the rest of the
system. On one of my systems with 512 Megs of memory in it I get the following:
(tigger pts9) # du -hs /proc
3.0K /proc
(tigger pts9) # ll -h kcore
-r-------- 1 root root 512M Aug 12 11:38 kcore
(tigger pts9) #
It looks to me like it is really using about 3k. If there really was a 512Meg
file in /proc I would not have any memory to run other programs.
IOW do not worry about it. There is nothing you can do about it short of
recompiling the kernel w/o /proc support. You do not want to do that on a normal
system as that would break a lot of other things that depend on /proc.
Does this make sense??
