Hi,

From what I have observed as well as been told is that nginx performs DNS resolution only once, upon startup. Is there some way to forge nginx to perform DNS lookups at a defined interval? The problem is that the ip addresses of our upstream servers change from time-to-time and this obviously causes problems. We don't have an option of making the upstream ip addresses static and having to restart nginx to fix these issues is something we are hoping we won't have to do.

Thanks

Well you got interesting point please some one please answer

Although I imagine you've resolved this already, for more info have a look at http://gc-taylor.com/blog/2011/11/10/nginx-aws-elb-name-resolution-resolvers/
