I am using nginx as proxy server. I got following error once:
   upstream timed out (110: Connection timed out) while connecting to

In what situtaion I will get this error? Exaple:
 1.  Upstream didn't accept connection within x time. 
Is there any other case when I can get this error or is it only one case
when I will get this error?
   1. Saving or reading to tmp file buffer was slow. 
   2. Nginx was running out of connection?
