Thanks Chad,
It seems that it will not return memory to applications, in fact, when
the kernel/buffer cache use the all memory, Applications use swap and
The scan rate is very high :
sar -g 3 ==>
pgscan/s = 5264
Now, I have this :
### top
last pid: 1107; load avg: 1.76, 1.66, 1.63; up
2+18:47:21 13:37:46
703 processes: 700 sleeping, 3 on cpu
CPU states: 66.6% idle, 11.5% user, 21.9% kernel, 0.0% iowait, 0.0% swap
Memory: 8192M phys mem, 2123M free mem, 16G total swap, 16G free swap
And *2123M free mem is incresing.*

Have you tried:
echo "::memstat" | mdb -k
Do this a few times over some interval to see if the kernel is growing.
Is there a reason you think the leak is in the buffer cache?
Do you have large, growing files in /tmp or a tmpfs mounted
file system? That can also eat up memory.
Do you have a large process that is growing?
You can use prstat -s size
or prstat -s rss
to see sorted memory usage of processes.

No, this is normal behavior. The buffer cache will grow to use all of
free memory. It won't steal memory from applications, though, and it
will return memory to the system for applications that need it.
