[Samba] Samba 3.0.14 (Debian Sarge) Memory Leakage

i have a question about memory.
When I launched the "top" command, I can see the following:
top - 16:08:47 up 135 days,  6:07,  1 user,  load average: 0.00, 0.00, 0.00
Tasks:  96 total,   1 running,  95 sleeping,   0 stopped,   0 zombie
Cpu(s):  0.3% us,  0.0% sy,  0.0% ni, 99.1% id,  0.5% wa,  0.0% hi,  0.0% si
Mem:   1036052k total,  1028580k used,     7472k free,   123376k buffers
Swap:  2000052k total,     8564k used,  1991488k free,   734732k cached

99% of my memory is used but It is impossible to see what proccess take
the amount of the memory when I see "%MEM" column

Hobbit, a monitoring tool, tells me that "physical" memory used is 99%
and "actual" memory used is 16%!!

Is somebody have explanations about this?

I know that if I stop smbd and restart it, my "physical" memory used 
raise to 0% and increase progressively.

Thanks a lot for your help in advance,

Since my upgrade to 3.0.23c the mentioned problems seem to be gone.
Nevertheless I will remove samba printers and stop cups support on the
misbehaving server as we do not depend on this service. I will then go
back to 3.0.14 and see if the problem persists.
Unfortunately I cannot let samba run under valgrind on this server
because it is a production system. Perhaps I can try to produce the
memory leakage on a test system.

Thanx for helping so far
