As informs me, the current reading is: [root@bck ~]# free -m total used free shared buffers cached Mem: 15936 15788 147 0 6746 438 -/+ buffers/cache: 8604 7332 Swap: 2047 0 2047 [root@bck ~]# [root@bck ~]# [root@bck ~]# echo 3 > /proc/sys/vm/drop_caches && service snmpd restart && free -m Stopping snmpd: [ OK ] Starting snmpd: [ OK ] total used free shared buffers cached Mem: 15936 509 15426 0 93 16 -/+ buffers/cache: 400 15536 Swap: 2047 0 2047 [root@bck ~]# I can not find the solution to release the memory buffer and cache memory so grateful for any hint for finding the solution to this "problem". -Paul
