[openMosix-general] Memory problem.

[Jozef I. <IVA...@de...>]

Hi oMers.,

I do not know if this is a already a know bug, but one of my friends show
me today following problem.
On kernel 2.4.25 as well as 2.4.27 starting process allocates some memory.
After stopping the process the freed memory is smaller then allocated. App.
12 k.

For example:

192:~# while :; do free; sleep 1; done
             total       used       free     shared    buffers     cached
Mem:        497804     434864      62940          0          0     291940
-/+ buffers/cache:     142924     354880
Swap:            0          0          0
             total       used       free     shared    buffers     cached
Mem:        497804     434872      62932          0          0     291940
-/+ buffers/cache:     142932     354872
Swap:            0          0          0
             total       used       free     shared    buffers     cached
Mem:        497804     434880      62924          0          0     291940
-/+ buffers/cache:     142940     354864
Swap:            0          0          0
             total       used       free     shared    buffers     cached
Mem:        497804     434888      62916          0          0     291940
-/+ buffers/cache:     142948     354856
Swap:            0          0          0
             total       used       free     shared    buffers     cached
Mem:        497804     434896      62908          0          0     291940
-/+ buffers/cache:     142956     354848
Swap:            0          0          0

At the and of the day node crash.

If I do the same on my old good 2.4.20 resulst is:

jozef@clue24:/$ while :; do free; sleep 1; done
                     total          used           free     shared

                      total         used           free     shared

So no memory is lost.

Is it feature or bug? :)

Or something discussed here some weeks ago and I just did not read it? :(

thanks

Jozef
