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.
So, in other words, there's no need to worry if a little swap is used
when the system's been running non-stop for a couple months?
It´s nothing unusual and a good thing when it means that stuff not
needed in memory is swapped out.
What is the advantage of emptying the cache supposed to be? I´ve
had servers with the uptime-counter flowing over after years of
uptime and never flushed the cache.
