We are using nginx/1.10.2 as web server on centos and redhat Linux 7.2 OS.
We are getting issues of getting our SWAP fully utilized even though we have
free memory , vm.swapiness is kept as default i.e. 60.
below are memory details for your reference :
# free -g
total used free shared buff/cache
Mem: 1511 32 3 361 1475
Swap: 199 199 0
Please suggest method by which we can avoid swap full scenario. also let us
know what should be vm.swapiness value for high load nginx web server. Also
let us know any other sysctl parameters to improve nginx performance.
