Strange memory issue(?) with 6850

[Dominique.GARNIER at arval.fr]

Hello,
 
I'm completely clueless about what's happening there. When i type a free
in some of our 6850
(Redhat Enterprise 4 AS U4 smp kernel x86_64 fully patched) i have
something looking like 
the following:
 
free
             total       used       free     shared    buffers
cached
Mem:       8158444    3251208    4907236          0     276884
835120
-/+ buffers/cache:    2139204    6019240
Swap:      6265340          0    6265340

So it seems that i have like 2Go of memory used BUT this is not the
case. Nothing is running
on the server right now apart from dell omsa. At the same time, we're
experiencing the 
aknowledged memory leak issue with OMSA (5.1.0) but i restarted it just
before doing this 'free'
and it released like 900Mo of memory. But i'm still left with another
2Go of memory used.

It's insteresting to notice that the servers not experiencing the memory
leak from OMSA do not
have this weird behaviour.

Last thing. After rebooting the 6850s the memory free come back to 8Go
free.

Is there any way for me to check where this memory is gone (apart from
the usual commands)? 
Is this something not released by OMSA at the restart time? Maybe i'm
missing something obvious
but i can't track where this memory is gone. 

Help would be appreciated thanks :)
