We need to change upstreams weight dynamicly(every 15 sec.), is that  
normal  
to reload nginx so frequently in prodution?

Not really, but this depends on your workload.

Every reload gracefully shutdowns old workers. This means that if  
there are long-lived requests (big downloads from clients with  
slow links etc.) old workers may still be here for a while. And  
they still consume memory and so on. In my practice shutdown time  
reached several hours in some cases.

If you reload every 15 seconds and shutdown takes longer - you  
have problem.

Thanks for the quick reply.  
But what is the right way for dynamic weight management of upstreams?
