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
