Since setting up Elastic Search, my swap usage has been increasing.
I've had it running since March 30th, and since then, my swap has gone up to 1GB of usage.
Using smem, it's JRE that is using most of the swap
I've made a change to sysctl to reduce the swappiness down to 20 (was set on the default 60) to try and stop processes using swap as aggressively, but has anyone else come across this?
