Nginx-1.6.0 Swapping

I have recently upgraded to Nginx-1.6.0 from 1.4.2 and I am seeing that
Nginx is swapping a lot. I have tried reducing vm.swappiness=0 but has
not
worked. This continues to happen on multiple servers that are running
Nginx-1.6.0:

First of all, please show “nginx -V” output and a configuration
you are using (or, better, minimal configuration you are able to
reproduce the problem with). Please also note that if you are
using 3rd party modules, next thing you’ll be asked about is to
try to reproduce the problem without them.

Some further debugging hints can be found here:
