Hi,
A few days ago I checked the health of my main public server running CentOS 7, a quad-core machine with 16 GB RAM. It had been running non-stop for 65 days, hosting only a handful of services (BIND, NTP, Apache, Postfix, Dovecot) for two domains.
I was surprised to see that RAM consumption was relatively high, and apparently, the machine even had to swap at some time.
I read up a bit on RAM consumption, and now I wonder if flushing the memory cache regularly is a good idea.

Any suggestions?
