Hi all,
there seems to be a strange behaviour in the way my system creates and
deletes files, as long as memory allocation is concerned.
running a simple script that continuously creates and deletes files on
tmpfs filesystem, a got the following results:
files created free memory on system
------------- ---------------------
0 48180
+6000 47936
+6000 47372
+6000 47372
+6000 47936
+6000 47936
+6000 47936
+6000 47936 (seems stable)
+9000 46976 (what on earth?)
+30000 45084
+80000 45084 (again stable)
+70000 39156 (not again...:( )
and sometime in the morning 25000 MB free RAM, and my system running too
slow
I am sure these are a lot a files and under normal conditions, there
will never be made and deleted so many.
It is that misbehavior of being stable for a long time and then again
allocating memory that concerns me.
I am running linux 2.4.26 on an x86 platform (gcc 3.2.3 uclib 0.9.20)
Simple sh file:
i=0
while [ 1 ] do
echo "dont allocate more memory please" > $i
rm $i
let i=$i+1
done
Any clue???
