Hello,
I 'm seeing couple of mysql db master swapping and using 3-4G of swap memory , but strangely db server has 4-5G free RAM available.
Any idea why mysql is using swap when server has enough ram .
Swappiness is set to 0 on these server .
[db1 ~]$ free -g
total used free shared buffers cached
Mem: 125 122 3 0 0 10
-/+ buffers/cache: 111 14
Swap: 15 4 11
