Can anyone confirm whether or not the below is cause for concern?

2012/01/09 13:21:13 [notice] 364#0: using inherited sockets from  
“/opt/nginx/ sbin/nginx”  
2012/01/09 13:21:13 [notice] 470#0: using inherited sockets from  
“/opt/nginx/ sbin/nginx”

Ideally could someone point me to documentation for Nginx  
warnings/notices.

Notices are normal (notification) messages.

In this case, an nginx binary is being replaced, as per

and a new binary gains control over listening sockets of the  
old binary.
