Unable to start service/access webgui after first system restart (and all after)

[GoogleCodeExporter]

Steps to reproduce:
1. Tried to manually start the service by running script. Also tried putting 
the start script "/usr/bin/ruby /opt/ovz-web-panel/utils/hw-daemon/hw-daemon.rb 
start" in rc.local

2. Output of "netstat -nlp|grep ruby" after system restart is
tcp        0      0 127.0.0.1:7767              0.0.0.0:*                   
LISTEN      1744/ruby

3. When running script manually, receive below message.

Starting the daemon...
/usr/lib/ruby/1.8/webrick/utils.rb:73:in `initialize': Address already in use - 
bind(2) (Errno::EADDRINUSE)

        from /opt/ovz-web-panel/utils/hw-daemon/hw-daemon.rb:272

4. Killed process from above, then ran script. Script ran fine, but still can't 
access service. Not sure where to go from here. Any help is appreciated.

Issue resolved. Ensure "localhost" remains in your /etc/hosts file, regardless 
of whatever else you have in there. Server will not run without "localhost" 
string.
