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. Is this any tools to know who use the big portion of RAM ?

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. Chad
