Why is this swapping?
Why is this swapping with 3GB+ free RAM?
RAM: 636MB / 3940MB
SWAP: 405MB / 4094MB
It seems to be mainly MySQL in swap.
Thanks.

There could have been a surge of traffic / queries that caused MySQL to use more RAM then what you had available thus causing it to use swap space?

Does it really matter? If performance is perfect don't worry about it. You are nit-picking in reality. No one can tell you why it's swapping. Probably just some misc OS stuff.

It happens on linux 2.6. If you google up 'swappiness' you'll get a better answer.

Unless your server is pure MySQL, I'd leave it as it is.

A few of mine do the same, it's strange...
Not high usage though, I think 10MB max on a master node.
