I have vast amounts of free memory, yet I keep catching kswapd

a tiny bit of swap (for no reason I can fathom):
MiB Mem : 15976.1 total, 979.6 free, 723.4 used, 14273.1
buff/cache MiB Swap: 32767.0 total, 32680.5 free, 86.5 used.
14920.2 avail Mem
This is with kernel 5.2.8-200.fc30.x86_64
I never noticed this before. Anyone know what is going on?
A guess only. The small amount of swap used is used by the swap
manager. And the 100% is the swap manager periodically cycling to see
if it is needed and checking swap status.
