No, but depending on your settings and compiled in modules it may  
be what you’ve asked it to do.

at the moment:

- Memory used…: 13761 MB / 32067 MB

service nginx reload = it doubles the ram usage.  
over a few days it use all 32gb of ram, and start with swap.

nginx.conf

}

Average total traffic out from server is 41.1 kb/s.  
on 12 vhosts/domains.

So what do i start with to find the problem?
