cached is getting high memory usage on CentOS
Posted on 2012-09-06
I'm running a Centos 5.5 with following hardware configuration,
Processor:- Inter(R) Xeon(TM) CPU 3.20GHz (16 CPUs),
Memory :- 32 GB
So, I noted cached memory use 26 GB, buffered memory use 1.65 GB, and free memory is onlu 1.21 GB available.
MemTotal: 32954572 kB
MemFree: 1219008 kB
Buffers: 1653304 kB
Cached: 26845304 kB
SwapCached: 0 kB
What does mean such a high cached memory?
Who's using this cached memory?
Is it normal this high cached memory?
I am afraid about this because I have Apache, nginx, Tomcat and Mysql On this server
thanks in advance
