Memory and Cache usage high

I've notice a sudden increase in RAM and CACHE usage that doesn't seem to be easing. I'm running CWP pro and this is on a Dell Power edge with 48gb DDR3 ram and dual Intel Xeon X5675 @ 3.07GHz
Apart from expected services I'm running:
SPF
DKIM
MOD Security
Nomit


Should I be concerned at this usage?

**UPDATE**

Found several instance of Netdata running on the server (funny as I've never installed Netdata). I have since uninstalled it and forced a reboot of the server and all seems fine again. Ram now running at 6% cache at 9% as expected.

Has anyone else had this happen to them?

Hi,

I have the same problem, also i don't use netdata.

Memory RAM (with Cache): 28.9GB / 32GB ( 90.3%)
Memory RAM (NO Cache): 28.14GB / 32GB ( 87.9%)
Swap Memory: 8.52GB / 118GB ( 7.2% )


Regrds,

I have the same problem

The RAM usage by caches is not a problem. It's okay. Just ignore it if you do not have any issues (i guess you do not have)
