I'm running nginx 1.2.6 behind amazon elb.
Periodically I see the following lines in nginx access.log:
10.28.135.252 - - [14/Jan/2013:14:20:07 +0000] "-" 400 0 "-" "-" "-"
10.28.135.252 - - [14/Jan/2013:14:20:07 +0000] "-" 400 0 "-" "-" "-"

10.28.135.252 - - [14/Jan/2013:14:20:48 +0000] "-" 400 0 "-" "-" "-"
There are no errors in the error log. What can it be?
Thanks.

the IP of the server running nginx?telnet hostname 80
and thenCTRL+D
to terminate the connection prematurely. Keep the log file open usingtail -F /var/log/nginx/yourlogfile.log
while you are testing with telnet. You should not be worried about these warnings though.
