I'm surprised because my system used the available RAM and then it even
began to swap.
Of course there is the possibility that you have discovered a bug
Minimal CentOS 7 installation with BIND, Apache, MySQL, Postfix and
Dovecot, regularly updated.
Hence my post. Wondering if other CentOS users experienced something
similar.
Every system that runs continuously for more that a few days will have some pages that were used once when some long-running process started and were never referenced again. Those pages will eventually migrate out to swap, and that's the best place for them. Right now, I see that this system has been up for 16 days and has ~270MB of swap used. I typically see ~500MB of swap used when the system has been running a while longer.
