Empty /error log lines (a lot of them)

Hi,

I also have a lot of these lines in my logs on all nginx webservers, 
they are a result of loadbalancers or nagios/icinga or something that is 
checking your webservers port for availability, some kind of half open 
connection without a full http request. If there would be any 
configuration setting to disable these entries that would be great, 
would save I/O and disk space ;-)
