Hi all,

Nginx has been working fine for months on my server. Recently, however, I see that "service nginx configtest" reports the following:

the configuration file /etc/nginx/nginx.conf syntax is ok
[emerg]: listen() to 0.0.0.0:17942, backlog 511 failed (98: Address already in use)
configuration file /etc/nginx/nginx.conf test failed


I believe nginx has been updated recently, but I'm not sure. It's currently at version 0.8.53. I've ran configtest before and have never seen this error. I need to add a new site in conf.d, but I fear that reloading or restarting afterwards will fail and my live sites will be down.

netstat -tlnp lists 0.0.0.0:17942 as in use by Program name "nginx.conf" (which seems weird, shouldn't this just say "nginx"). Also, if I rename the conf.d/site.conf file that includes the 17942 port entry, it just fails on the next conf down the line on the following ip/port.

Now that I've typed out the entire problem, it occurs to me that the problem could be the misnamed Program name. Maybe nginx thinks that a different program is occupying those ports because the name is not "nginx". Does that seem likely? Also, was there a bug fixed somewhere that resolved/caused the name change? I have a hunch that restarting nginx will solve the problem, but I don't want to risk it since it's a live server.

Any ideas? Thank you for reading.
