Subject: need help to clear kernel (2.6.16.17) cached memory

Hi,

on my system (based on 2.6.16.17), i am trying to clear the cached
memory but it is not being cleared.

mars# free -m
             total       used       free     shared    buffers     cached
Mem:           925        459        465          0          0        231
-/+ buffers/cache:        228        697
Swap:            0          0          0
mars# sync && echo 3 > /proc/sys/vm/drop_caches
M1450-mrakesh# free -m
             total       used       free     shared    buffers     cached
Mem:           925        459        466          0          0        231
-/+ buffers/cache:        227        697
Swap:            0          0          0

could you please let me know what i am missing here? as per my
investigation writing 3 to drop_caches should clear the cached memory.

thanks,
manish
